DC voltage limits of the drive
U
ac
: AC input voltage. Set also parameter 95.01 Supply voltage in the drive control program to this value. All
drives on the common DC system must have the same setting. Set parameter 95.02 Adaptive voltage limits to
Disabled.
U
dc
: Nominal DC link voltage = 1.35 × U
ac
in normal motoring operation mode of the drive.
U
DC,chr
: Charging limit. Drive opens the charging circuit when the DC voltage reaches this limit at power up.
U
DC,ovc
, U
DC,uvc
: Overvoltage control limit and Undervoltage control limit. The overvoltage and undervoltage
control of the DC link voltage level are enabled by default. The drive limits the motoring and generating torque
when necessary to keep the DC link voltage within the control limits. When a brake chopper and resistor are in
use, you must disable the overvoltage control.
U
DC,ovt
, U
DC,uvt
: DC overvoltage trip limit and DC undervoltage trip limit. The drive trips and gives a fault
message if the DC link voltage reaches these levels.
U
DC,brcl
, U
DC,brch
: Brake chopper limit low and Brake chopper limit high. The brake chopper starts operation
when the DC link voltage reaches the low level and you have enabled the chopper with the drive parameter. If
the DC link voltage level reaches the high level, the brake chopper will be at its maximum load.
