ACSM1 DC voltage limits

All ACSM1 drive modules have own terminals for the DC connection.
Different limit values in ACSM1 drive modules related to DC voltage level
are defined in the table below. Please see ACSM1 firmware manual for the
more detailed descriptions.
Designation
Nominal DC voltage
DC voltage range
Charging limit
DC voltage control: Over voltage
control limit
DC voltage control: Under voltage
control limit
DC over voltage trip limit
DC under voltage trip limit
Braking chopper limit, low
Braking chopper limit, high
U in the column ("Value"), where the values are defined, is based on the
dc
ACSM1 drive module setting for the used supply voltage. The used supply
voltage can be set by parameter (Par. 47.03 and 47.04) or identified
automatically. Used U
U = 1.35 x (signal: 1.19 USED SUPPLY VOLT)
