For SINAMICS S150 cabinet units with line-side Active Line Module, the current controller clock cycle and the
pulse frequency of the Active Line Module are set at the factory to the values given in the table:
Line supply
voltage
S150 output Rectifier/regenerative
current
Rated output current ALM current
controller
clock cycle
ALM pulse
frequency
380 V – 480 V 3AC 110 kW – 250 kW 197 A – 447 A 210 A – 490 A 250 μs 4.00 kHz
315 kW
– 800 kW 549 A – 1262 A 605 A – 1405 A 400 μs 2.50 kHz
500 V – 690 V 3AC 75 kW – 315 kW 86 A – 304 A 85 A – 330 A 250 μs 4.00 kHz
400 kW – 1200 kW 375 A – 1142 A 410 A – 1270 A 400 μs 2.50 kHz

With option L04 the ALM of the S150 cabinet unit 315 kW (380 V – 480 V) operates with a current controller clock cycle of 250 μs and a pulse frequency of 4.00 kHz
Factory setting of ALM current controller clock cycle and ALM pulse frequency for SINAMICS S150 cabinet units
Parameter p0092 (Clock synchronous operation pre-assignment/check) is the only means by which the factory
setting can be slightly changed. This parameter allows the current controller clock cycle to be changed from 400 μs to
375 μs to enable isochronous PROFIdrive operation. Changing this setting slightly increases the pulse frequency for
these devices from 2.50 kHz to 2.67 kHz.
