6 Parameters
Par. Description Minimum Maximum Default Units
P-33 Spin Start 0 2 0 -
0 : Disabled
1 : Enabled. When enabled, on start up the drive will attempt to determine if the motor is already rotating, and will begin to control
the motor from its current speed. A short delay may be observed when starting motors which are not turning.
2 : Enabled on Trip, Brown Out or Coast Stop. Spin start is only activated following the events listed, otherwise it is disabled.
P-34 Brake Chopper Enable (Not Size 1) 0 4 0 -
0 : Disabled
1 : Enabled With Software Protection. Enables the internal brake chopper with software protection for a 200W continuous rated
resistor
2 : Enabled Without Software Protection. Enables the internal brake chopper without software protection. An external thermal
protection device should be fitted.
3 : Enabled With Software Protection. As setting 1, however the Brake Chopper is only enabled during a change of the frequency
setpoint, and is disabled during constant speed operation.
4 : Enabled Without Software Protection. As setting 2, however the Brake Chopper is only enabled during a change of the frequency
setpoint, and is disabled during constant speed operation.
P-35 Analog Input 1 Scaling / Slave Speed Scaling 0.0 2000.0 100.0 %
Analog Input 1 Scaling. The analog input signal level is multiplied by this factor, e.g. if P-16 is set for a 0 – 10V signal , and the scaling
factor is set to 200.0%, a 5 volt input will result in the drive running at maximum frequency / speed (P-01)
Slave Speed Scaling. When operating in Slave Mode (P-12 = 9), the operating speed of the drive will be the Master speed multiplied
by this factor, limited by the minimum and maximum speeds.
P-36 Serial Communications Configuration See Below
Index 1 : Address 0 63 1 -
Index 2 : Baud Rate 9.6 1000 115.2 kbps
Index 3 : Communication loss protection 0 3000 t 3000 ms
This parameter has three sub settings used to configure the Modbus RTU Serial Communications. The Sub Parameters are
1st Index : Drive Address : Range : 0 – 63, default : 1
2
nd
Index : Baud Rate & Network type : Selects the baud rate and network type for the internal RS485 communication port.
For Modbus RTU : Baud rates 9.6, 19.2, 38.4, 57.6, 115.2 kbps are available.
For CAN Open : Baud rates 125, 250, 500 & 1000 kbps are available.
3
rd
Index : Watchdog Timeout : Defines the time for which the drive will operate without receiving a valid command telegram to
Register 1 (Drive Control Word) after the drive has been enabled. Setting 0 disables the Watchdog timer. Setting a value of 30, 100,
1000, or 3000 defines the time limit in milliseconds for operation. A ‘t
tt
t’ suffix selects trip on loss of communication. An ‘r
rr
r’ suffix
means that the drive will coast stop (output immediately disabled) but will not trip.
P-37 Access Code Definition 0 9999 101 -
Defines the access code which must be entered in P-14 to access parameters above P-14
P-38 Parameter Access Lock 0 1 0 -
0 : Unlocked. All parameters can be accessed and changed
1 : Locked. Parameter values can be displayed, but cannot be changed except P-38.
P-39 Analog Input 1 Offset -500.0 500.0 0.0 %
Sets an offset, as a percentage of the full scale range of the input, which is applied to the analog input signal. This parameter
operates in conjunction with P-35, and the resultant value can be displayed in P00-01.
The resultant value is defined as a percentage, according to the following :-
P00-01 = (Applied Signal Level(%) - P-39) x P-35)
P-40 Index 1 : Display Scaling Factor 0.000 16.000 0.000 -
Index 2 : Display Scaling Source 0 3 0 -
Allows the user to program the VersiDrive i E3 to display an alternative output unit scaled from either output frequency (Hz), Motor
Speed (RPM) or the signal level of PI feedback when operating in PI Mode.
Index 1 : Used to set the scaling multiplier. The chosen source value is multiplied by this factor.
Index 2 : Defines the scaling source as follows :-
0 : Motor Speed. Scaling is applied to the output frequency if P-10 = 0, or motor RPM if P-10 > 0.
1 : Motor Current. Scaling is applied to the motor current value (Amps)
2 : Analog Input 2 Signal Level. Scaling is applied to analog input 2 signal level, internally represented as 0 – 100.0%
3 : PI Feedback. Scaling is applied to the PI feedback selected by P-46, internally represented as 0 – 100.0%
P-41 PI Controller Proportional Gain 0.0 30.0 1.0 -
PI Controller Proportional Gain. Higher values provide a greater change in the drive output frequency in response to small changes
in the feedback signal. Too high a value can cause instability
P-42 PI Controller Integral Time 0.0 30.0 1.0 s
PI Controller Integral Time. Larger values provide a more damped response for systems where the overall process responds slowly
P-43 PI Controller Operating Mode 0 1 0 -
0 : Direct Operation. Use this mode if when the feedback signal drops, the motor speed should increase.
1 : Inverse Operation. Use this mode if when the feedback signal drops, the motor speed should decrease.
P-44 PI Reference (Setpoint) Source Select 0 1 0 -
Selects the source for the PID Reference / Setpoint
0 : Digital Preset Setpoint. P-45 is used
1 : Analog Input 1 Setpoint. Analog input 1 signal level, readable in P00-01 is used for the setpoint.
P-45 PI Digital Setpoint 0.0 100.0 0.0 %
When P-44 = 0, this parameter sets the preset digital reference (setpoint) used for the PI Controller as a % of the feedback signal.
