Table 7- 28 Setting the control logic of the motor holding brake
Parameter
Description
p1215 = 1
Enable motor holding brake
0 Motor holding brake locked (factory setting)
1 Motor holding brake just like the sequence control
2: Motor holding brake permanently open
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 ru brake release time
p1217
Motor holding brake closing time (factory setting 0.1 s)
p1217 > braking signal relay ru brake closing time
r0052.12
"Open motor holding brake" command
Table 7- 29 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)
p1226
Stationary state detection speed threshold (factory setting 20 rpm)
When braking with OFF1 or OFF3, when the speed falls below this threshold, stand-
still is detected and the monitoring time p1227 or p1228 is started
p1227
Stationary state detection monitoring time (factory setting 300 s)
p1228
Pulse deletion delay time (factory setting 0.01 s)
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.
