Inverter with CU240B-2 and CU240E-2 Control Units
Operating Instructions, 01/2011, FW 4.4, A5E02299792B AB
Control logic parameters of the motor holding brake
Description
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
Motor holding brake opening time (factory setting 0.1 s)
p1216 > braking signal relay runtimes + brake release time
Motor holding brake closing time (factory setting 0.1 s)
p1217 > braking signal relay runtimes + brake closing time
"Open motor holding brake" command
Advanced settings
Description
Magnetizing time (factory setting 0 s)
During this time the induction motor is magnetized. The inverter calculates this
parameter using p0340 = 1 or 3.
Open motor holding brake (imperative) (factory setting 0)
Close motor holding brake (imperative) (factory setting 0)
Stationary state detection speed threshold (factory setting 20 rpm)
When braking with OFF1 or OFF3, when the speed falls below this threshold,
standstill is detected and the monitoring time p1227 or p1228 is started
Stationary state detection monitoring time (factory setting 300 s)
Pulse deletion delay time (factory setting 0.01 s)
Starting frequency of 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.
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.
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.
