Table 6-29 Control logic parameters of the motor holding brake
Parameter Description
p1215 = 3 Enable motor holding brake
0 Motor holding brake locked (factory setting)
3: Motor holding brake just like the sequential control, connected via BICO
p1216 Motor holding brake opening time (factory setting 0.1 s)
p1216 > braking signal relay runtimes + brake release time
p1217 Motor holding brake closing time (factory setting 0.1 s)
p1217 > braking signal relay runtimes + brake closing time
r0052.12 "Open motor holding brake" command
p0730 = 52.12 Signal source for terminal DO 0
Control motor holding brake via digital output 0
p0731 = 52.12 Signal source for terminal DO 1
Control motor holding brake via digital output 1
Table 6-30 Advanced settings
Parameter Description
p0346 Magnetizing time (factory setting 0 s)
During this time the induction motor is magnetized. The inverter calculates this pa‐
rameter using p0340 = 1 or 3.
p0855 Open motor holding brake (imperative) (factory setting 0)
p0858 Close motor holding brake (imperative) (factory setting 0)
p1351 Starting frequency, motor holding brake (factory setting 0%)
Setting the frequency set value at the slip compensation output when starting with
motor holding brake.
When the parameter p1351 is set to > 0, slip compensation is automatically switched
on.
p1352 Starting frequency for motor holding brake (factory setting 1351)
Setting the signal source for the frequency set value at the slip compensation output
when starting with motor holding brake.
p1475 Speed controller torque set value for motor holding brake (factory setting 0)
Setting the signal source for the torque set value when starting with motor holding
brake.
