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
