SINAMICS G120 Control Units CU240S, Edition 05/2007
Description: Displays motor start-up time.
This time corresponds to the standardized motor inertia.
The start-up time is the time taken to reach rated motor speed from standstill at acceleration with rated motor torque
(r0333).
Description: Sets magnetization time [s], i.e. waiting time between pulse enable and start of ramp-up.
Motor magnetization builds up during this time. Magnetization time is normally calculated automatically from the
motor data and corresponds to the rotor time constant.
Notice: An excessive reduction of this time can result in insufficient motor magnetization.
Note: If boost settings are higher than 100 %, magnetization time may be reduced.
Default value is depending on inverter type and its rating data.
Description: Changes time allowed after OFF2 / fault condition, before pulses can be re-enabled.
Notice: Not active following a normally completed ramp-down, e.g. after OFF1, OFF3 or JOG.
Overcurrent trips will occur if the time is decreased excessively.
Note: The demagnetization time is approximately 2.5 x rotor time constant in seconds.
Default value is depending on inverter type and its rating data.
