7.6 Selecting physical units
The following options are available:
●
●
●
Restrictions
● The motor standard, the unit system, as well as the process variables can only be
changed with the STARTER in offline mode.
● The values on the rating plate of the inverter or motor cannot be displayed as percentage
values.
● The repeated change of the unit (e.g.: Percent → physical unit 1 → physical unit 2 →
percent) may lead to rounding errors.
Reference variables for unit changeover
p2000 Reference frequency/speed
p2001 Reference voltage

Description
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.
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, stand-
still 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, 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.
