Open-loop Drive A1
50
MTR TORQUE LIMIT
(Motoring Current Limit)
This parameter sets the motoring current limit as
a percentage of the drive’s rated current. This
parameter helps define the Stall Prevention
(Current Limit) function. Stall prevention causes
the drive to deviate from the commanded speed
to limit motor current to a user set level. When
the motoring current limit is reached (MTR
TORQUE LIMIT(A1)), the stall prevention
function will reduce speed. Also, the
responsiveness of the stall prevention function is
determined by the Current Limit Integral Gain
(ILIMT INTEG GAIN(A4)) parameter.
REGEN TORQ LIMIT
(Regenerating Current Limit)
This parameter sets the regenerative current
limit as a percentage of the drive’s rated current.
This parameter helps define the Stall Prevention
(Current Limit) function. Stall prevention causes
the drive to deviate from the commanded speed
to limit motor current to a user set level. When
the regenerating current limit is reached
(REGEN TORQ LIMIT(A1)), the stall prevention
function will increase speed in an effort to shed
load. Stall prevention can optionally be disabled
in regeneration by the Stall Prevention Regen
Enable (STALLP REGEN ENA(C1)) parameter.
Also, the responsiveness of the stall prevention
function is determined by the Current Limit
Integral Gain (ILIMT INTEG GAIN) parameter.

FLT RESET DELAY
(Fault Reset Delay)
When the drive is set for automatic fault reset,
this is the time before a fault is automatically
reset.
FLT RESETS/HOUR
(Fault Resets per Hour)
When the drive is set for automatic fault reset,
this is the number of faults that is allowed to be
automatically reset per hour.
UP TO SPD. LEVEL
(Up to Speed Level)
This parameter sets the threshold for the up to
speed logic output. This is only used to
generate the up to speed logic output.
TRQ LIM MSG DLY
(Torque Limit Message Delay)
This parameter will delay posting the Torque
Limit Hit message for the time set by this
parameter. This prevents nuisance postings of
this alarm message.
ENCODER PULSES
(Encoder Pulses)
Only used for diagnostics…
This parameter sets the pulses per revolution
(before the x4 logic) the drive receives from the
encoder for only by the ENCODER SPEED (D1)
display.
