7 - PARAMETER DESCRIPTION
LCD Display
Range 0.00 to Max Frequency (Default 3.0Hz)
Description Current Limit Frequency. This parameter sets the frequency when the current limit becomes active. This
value will also be the frequency point the drive will decelerate the motor to during Motoring Current.
LCD Display
Range 0.1 - 3200 seconds (Default 1.0s)
Description Ramp Time in current limit. This parameter defines the ramp rate when the drive enters current limit
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.
LCD Display
Range 0 - 50% (Default 10%)
Description Current Limit Minimum. This parameter sets the minimum amount of current limit when the current limit
amount is determined by an analog input.

Range
100% - 1000%
(Default 300%)
Description Regenerative timeout. This parameter operates as a percentage of the longest ramp time. This time then
defines the amount of time a deceleration to stop can take without causing a Regen Timeout fault. For
example, if Decel Time 1 is 5.0 seconds, Decel Time 2 is 10.0 seconds, and Max Regen Ramp is 300%, a
deceleration to stop that takes more than 30 seconds will cause a Regen Timeout fault in the drive.
