600 Current Lim Sel
Default: Fixed Lvls
Range: n/a
Level 2
The Vacon 500x drive provides a Current Limit feature. With this feature enabled, the drive’s frequency is
automatically reduced when operating in motoring mode to keep the measured torque within limits. When
operating in regenerative mode, the output frequency can be automatically increased for the same reason.
In addition to the current limit parameters that activate the Current Limit mode, more current limit
parameters are available to adjust the drive’s response to the load demands. The following data values may
be assigned to this parameter:
Parameter Value
Description
Fixed LvlsThe fixed levels set in parameters 601, 602, 603 and 604 determine the current limit in each of the four
quadrants of operation.
Vin2 Vin2 analog input sets the current limit value, range 0-200%
Cin Cin analog input sets the current limit value, range 0-200%
Vin2 MotorVin2 analog input sets the motoring current limit value, range 0-200%
Cin MotorCin analog input sets the motoring current limit value, range 0-200%
Vin2 F-MtrVin2 analog input sets the FWD motoring current limit value, range 0-200%
Cin F-MotorCin analog input sets the FWD motoring current limit value, range 0-200%
601 Cur Lim Mtr Fwd
Default: 120%
Range: 5-150%
Level 2
This parameter sets the current limiting point when the drive is in motoring mode in the forward direction.
The limit is expressed as a percentage of the current capacity of the drive.
602 Cur Lim Mtr Rev
Default: 120%
Range: 5-150%
Level 2
This parameter sets the current limiting point when the drive is in motoring mode in the reverse direction.
The limit is expressed as a percentage of the current capacity of the drive.
603 Cur Lim Reg Fwd
Default: 80%
Range: 5-150%
Level 2
This parameter sets the current limiting point when the drive is in regenerative mode in the forward
direction. The limit is expressed as a percentage of the current capacity of the drive.
604 Cur Lim Reg Rev
Default: 80%
Range: 5-150%
Level 2
This parameter sets the current limiting point when the drive is in regenerative mode in the reverse
direction. The limit is expressed as a percentage of the current capacity of the drive.
605 Cur Lim Freq
Default: 3.0 Hz
Range: 0.0 - 400.0 Hz
Level 2
This parameter sets the frequency where current limit becomes active. This value will also be the frequency
point the drive will decelerate the motor to during Motoring Current Limit.
606 Ramp Time CL
Default: 1.0 sec
Range: 0.1-3200.0 sec
Level 2
This parameter determines the ramp rate when the drive enters Current Limit, and defines the ramping
rate of the drive when in a current limiting mode. If the drive is in regenerative current limit, it is an
acceleration time. If the drive is in motoring current limit, it is a deceleration time.
607 Cur Lim Minimum
Default: 10%
Range: 0 - 50%
Level 2
This parameter limits the lowest amount of current (or Torque) limiting that can occur when the limit
threshold is determined by an analog input.
