9.2 Brake Activation
How to parameterize
brake activation….
The brake is always switched on and off with the system enable A900. In this case brake
release and brake set times are ignored.
To specify the physical factors of motor and brake, parameterize activation of the brake
on page 9.2 of the Assistant (Figure 9-3).
Remember that the screen on page 9.2 depends on the particular control mode which is
set (B20 control mode). The screen shown in Figure 9-3 is the one which appears when
a control mode without feedback is parameterized in B20 (B20 = 0:V/f control or 1:
sensorless vector control). If you set a control mode with feedback in B20
(B20 = 3:vector control or 64:servo control), the parameters F01 and F02 do not appear
on page 9.2 and the characteristic curves are different.
The brake activation as you parameterized it on page 9.2 is triggered with the system
enable A900, a stop (signal source set in D102 stop source) or a quick stop (signal
source set in A62 quick stop source).
To parameterize proceed as described below:
• Activate brake activation in parameter F08. In the setting 1:active the current motor
torque is stored when the brake closes. This torque is re-established when the brake
opens again. When F08 is set to 2:do not save torque only the motor magnetization
(flux) is established when the brake opens.
• Enter the speed in F02 at which the brake is to be applied.
• Enter the speed in F01 at which the brake is to be released.
• Enter the time in B27 during which the motor is to remain magnetized (in flux) after the
brake procedure is triggered.
• Enter the percentage of the halt flux in B25 which is to be maintained after the time in
B27.
• Enter the time in F07 which the brake requires to be applied.
• Enter the time in F06 which the brake requires to be released.
If you use the motors with brakes from STÖBER ANTRIEBSTECHNIK GmbH & Co. KG,
you will find the correct values for F07 and F06
in the catalogs.
If you use a servo motor with EnDat
®
encoder, F07 and F06 are automatically read from
the electronic nameplate.
