Use of axis modules ≤ MDA90A.. size 5 on power supply module MDP90A.. size 4

If the axis modules ≤ MDA90A-1000.. are operated with a PWM frequency of 4 kHz, the following restrictions need not be observed.

If axis modules ≤ MDA90A-1000.. (size 5) with a PWM frequency of 8 or 16 kHz are operated on a supply module MDP90A-1100.. (size 4), either directly in series or to the right of an axis module ≥ MDA90A-1400.., note that the sum of the nominal DC link currents I_{DCL_nom} of the axis modules ≤ MDA90A-100.. (size 5) must not exceed the value of 153 A.

Example 1
Modules	Nominal DC link current
MDP90A-1100..	–
MDA90A-0640..	I_{DCL_nom} = 64 A
MDA90A-0640..	I_{DCL_nom} = 64 A
MDA90A-0240..	I_{DCL_nom} = 24 A
Total	I_{DCL_nom} = 152 A → The setup is permitted.

Example 2
Modules	Nominal DC link current
MDP90A-1100..	–
MDA90A-1400..	I_{DCL_nom} = 64 A
MDA90A-0640..	I_{DCL_nom} = 64 A
MDA90A-0640..	I_{DCL_nom} = 64 A
MDA90A-0640..	I_{DCL_nom} = 64 A
Total	I_{DCL_nom} = 192 A → The setup is not permitted.
