Issue 10/06 3.13 3 Functions Motor holding brake (MHB) Parameter range: Warnings Faults Function chart number: P1215 P0346, P1216, P1217, P1080 r0052 bit 12 - For drives which must be secured when powered-down to prevent them undesirably moving, the MICROMASTER brake sequence control (enabled via P1215) can be used to control the motor holding brake. Before opening the brake, the pulse inhibit must be removed and a current impressed which keeps the drive in that particular position.
PAGE 142
3 Functions Issue 10/06 The motor holding brake is either closed using OFF1 / OFF3 or OFF2. For OFF1 / OFF3, when the minimum frequency P1080 is reached, the motor is operated at this frequency until the brake has been applied (closing times of brakes lie between 15 ms and 300 ms). The actual time is specified using parameter P1217 "Holding time after ramp down" (refer to Fig. 3-58).
PAGE 143
Issue 10/06 3 Functions NOTE Motors have optional holding brakes which are not designed to be used as brakes for normal operation. The holding brakes are only designed for a limited number of emergency braking operations / motor revolutions with the brake closed (refer to the Catalog data). When commissioning a drive with integrated holding brake it is therefore absolutely imperative that it is ensured that the holding brake functions perfectly.
PAGE 144
3 Functions Issue 10/06 WARNING It is not sufficient to select the status signal r0052 bit 12 "Motor holding brake active" in P0731 – P0733. In order to activate the motor holding brake, in addition, parameter P1215 must also be set to 1. If the frequency inverter controls the motor holding brake, then a commissioning may not be carried-out for potentially hazardous loads (e.g. suspended loads for crane applications) unless the load has been secured.
PAGE 145
Issue 10/06 3 Functions Set the load holding The opening / closing times of mechanical brakes are subject to certain fluctuations; this is the reason that a weight equalization function must be parameterized in the frequency inverter for the time P1216 and P1217. The following parameters must be defined so that the axis cannot sag (i.e. the axis cannot drop/fall).
PAGE 146
3 Functions Issue 10/06 If the frequency inverter directly controls the motor holding brake using the relay integrated in the frequency inverter, then the max. load capability of this relay should be carefully taken into consideration in conjunction with the voltage/current data of the holding brake. The following applies for the relay integrated in the frequency inverter: − 30 V DC / 5 A − 250 V AC / 2 A If this value is exceeded, an additional relay should, for example, be used.
PAGE 147
Issue 10/06 3.14 3 Functions Electronic brakes MICROMASTER 420 has 2 electronic brakes: DC braking (refer to Section 3.14.1) Compound braking (refer to Section 3.14.2) These brakes can actively brake the drive and avoid a possible DC link overvoltage condition. An inter-dependency as shown in Fig. 3-62 is present. DC braking P1233 > 0 ? yes DC braking enabled Fig. 3-62 3.14.
PAGE 148
3 Functions Issue 10/06 The DC brake can therefore support a braking operation from approx. < 10 Hz or prevents / minimizes the increase in the DC link voltage for regenerative braking. This is realized because energy is directly absorbed in the motor. The essential advantage and the main application of the DC brake is the fact that a holding torque can be generated at standstill (0 Hz).
PAGE 149
Issue 10/06 3 Functions Sequence 2 1. Enabled and selected using BICO parameter P1230 (refer to Fig. 3-64) 2. The inverter pulses are inhibited for the duration of the de-magnetizing time P0347. 3. The requested braking current P1232 is impressed for the time selected and the motor is braked. This state is displayed using signal r0053 bit 00. 4. After DC braking has been cancelled, the drive accelerates back to the setpoint frequency until the motor speed matches the drive inverter output frequency.
PAGE 150
3 Functions 3.14.2 Issue 10/06 Compound braking Parameter range: Warnings Faults Function chart number: P1236 - For compound braking (this is enabled using P1236) DC braking is superimposed with regenerative braking (where the drive regenerates into the line supply as it brakes along a ramp). If the DC link voltage exceeds the compound switch-in threshold VDC-Comp (refer to Fig. 3-65), then a DC current is impressed as a function of P1236.
PAGE 151
Issue 10/06 3 Functions WARNING For compound braking, regenerative braking is superimposed on the DC braking (braking along a ramp). This means that components of the kinetic energy of the motor and driven load are converted into thermal energy in the motor.

Any faults are automatically acknowledged by the drive inverter.
PAGE 153
Issue 10/06 3 Functions The number of start attempts is specified using parameter P1211. The number is internally decremented after each unsuccessful attempt. After all attempts have been made (as specified in parameter P1211), automatic restart is cancelled with message F0035. After a successful start attempt, the counter is again reset to the initial value. NOTE The "Flying restart" function (refer to Section 3.

PAGE 157
Issue 10/06 3 Functions On the other hand, if the Vdc_max controller increases the output frequency (e.g. for a steady-state regenerative load), then the Vdc_max controller is disabled by an internal drive inverter monitoring function and warning A0910 is output. If the regenerative load continues, the drive inverter is protected using fault F0002. In addition to controlling the DC link, the Vdc_max controller supports the stabilizing processes of the speed at the end of an acceleration phase.

3 Functions 3.19 Issue 10/06 Thermal motor protection and overload responses Parameter range: Warnings Faults Function chart number: P0610 – P0614 P0345 r 0034 A0511 F0011 - MICROMASTER 420 has a completely new integrated concept for thermal motor protection. There are numerous possibilities of effectively protecting the motor but at the same time ensuring high motor utilization.
PAGE 161
Issue 10/06 3 Functions Using these simplifications, the thermal motor behavior can be defined using a 1st Order filter (PT1 filter). In this case, the square of the normalized motor current (measured motor current r0027 divided by the rated motor current P0305) weighted by the thermal motor time constant P0611 results in the I²t value of the motor r0034. The I²t value represents a parameter for the temperature rise / temperature of the motor.
PAGE 162
3 Functions Issue 10/06 Temperature Classes The permissible temperature rise of electrical machinery (motors) is limited due to the thermal strength of the insulating materials. Different maximum values are permissible depending on the material used. In compliance with regulations for rotating electrical machinery, a differentiation is made between several temperature Classes (refer to the motor rating plate) and these are assigned to the highest permissible continuous temperature.

Parameterizable responses are provided to the user which allows the drive system to be still operated at the power limit thus avoiding immediate shutdown.
PAGE 166
3 Functions Issue 10/06 When an overload occurs regarding one of these monitoring functions, initially, a warning is output.

Issue 10/06 3 Functions No reduction (P0290 = 1) This option should be selected if neither a reduction in the pulse frequency nor a reduction in the output current is being considered. In this case, the drive inverter does not change its operating point after the warning threshold has been exceeded so that the drive can be further operated until the shutdown values are reached. After the shutdown threshold has been reached, the drive inverter shuts down (trips) with fault F0004.
