p1350[0...n] Soft starting / Soft starting
Access level: 3
Can be changed: U, T
Units group: -
Min
0
Description: Sets whether the voltage is continuously increased during the magnetizing phase (p1350 = 1, On) or whether it
jumps directly to the voltage boost (p1350 = 0, Off).
Value: 0:
1:
Note: The settings for this parameter have the following advantages and disadvantages:
0 = off (jump directly to voltage boost)
Advantage: Flux is established quickly -> torque is quickly available
Disadvantage: The motor can move while it is being magnetized
1 = on (voltage is continually established)
Advantage: The motor is unlikely to rotate
Disadvantage: The flux is established slower -> torque is available later
p1351[0...n] CO: Motor holding brake starting frequency / Brake f_start
Access level: 3
Can be changed: U, T
Units group: -
Min
-300.00 [%]
Description: Sets the frequency setting value at the slip compensation output for starting up with motor holding brake.
Dependency: When setting p1351 > 0, then slip compensation is automatically activated (p1335 = 100 %).
Refer to: p1352
Notice: A BICO interconnection to a parameter that belongs to a drive data set always acts on the effective data set.
Note: Connected with p1352 a value of 100% corresponds to the motor rated slip (r0330).
p1352[0...n] CI: Motor holding brake starting frequency signal source / Brake f_start
Access level: 3
Can be changed: T
Units group: -
Min
-
Description: Sets the signal source for the frequency setting value at the slip compensation output for starting up with motor
holding brake.
Dependency: Refer to: p1216
Note: A value of 100% corresponds to the motor rated slip (r0330).
The setting of the starting frequency begins after magnetizing (see p0346, r0056.4) and ends once the brake open-
ing time (p1216) has elapsed and the starting frequency (p1334) has been reached.
A setting value of zero means that no setting procedure will take place.
