When all conditions mentioned are fulfilled, the brake test can be started by setting the
input BRK_bBrakeTest to TRUE.
[9-20] Sequence of the brake test
Error behaviour
r When the stop position of the motor axis has changed during the brake test by more
than the permissible angle of rotation set in C02595 despite the applied brake:
– The brake test is aborted immediately and the controller is inhibited.
– The status "position drift when brake is applied" is displayed at the status output
BRK_dnState via bit 21 and the status "brake error" is displayed via bit 15.
– The output BRK_bError is set to TRUE.
r By resetting the input BRK_bBrakeTest to FALSE an error can be reset automatically.
Normal behaviour
Error behaviour
n C02594 : Test torque
o C02595 : Permissible angle of rotation
CINH = controller inhibit
r The specified test torque is created via
a ramp generator with an acceleration
time of 1 s and held max. 4 s.
– By this it is tried to rotate the motor
shaft while the brake is applied.
r By resetting the input BRK_bBrakeTest
to FALSE the brake test can be aborted.
