Rockwell Automation 1336E IMPACT Adjustable Frequency AC Drive User Manual V 1-4.XX - Manual (Page 225)

Parameters 11-27
72 Pos Mtr Cur Lim
Enter the largest allowable positive motor stator current up to
200% or 400% as determined by Max Mtr Current
(parameter 195). Values over 150% of the inverter rated current
(or 135% for the 460V/800HP H frame) may not be attainable.
Bit 0 in Torque Limit Sts (parameter 87) indicates when Pos Mtr
Cur Lim is actively restricting current.
Changing Pos Mtr Cur Lim affects Pos Torque Lim
(parameter 74). If you lower Pos Mtr Cur Lim, you may also lower
the range of Pos Torque Lim. If you then raise Pos Mtr Cur Lim,
Pos Torque Lim may remain at the lower value due to the range
change.
You cannot change this value while the drive is running.

73 Neg Mtr Cur Lim
Enter the largest allowable negative motor stator current up to
200% or 400% as determined by Max Mtr Current
(parameter 195). Values over 150% of the inverter rated current
(or 135% for the 460V/800HP H frame) may not be attainable.
Bit 0 in Torque Limit Sts (parameter 87) indicates when Neg Mtr
Cur Lim is actively restricting current.
Changing Neg Mtr Cur Lim affects Neg Torque Lim
(parameter 75). If you lower Neg Mtr Cur Lim, you may also lower
the range of Neg Torque Lim. If you later raise Neg Mtr Cur Lim,
Neg Torque Lim may remain at the lower value due to the range
change.
You cannot change this value while the drive is running.

74 Pos Torque Lim
Enter the torque limit for positive torque reference values. The
positive motor torque reference will not be allowed to exceed this
value. Pos Mtr Cur Lim (parameter 72) affects the maximum
value of Pos Torque Lim.

75 Neg Torque Lim
Enter the the torque limit for the negative torque reference
values. The negative motor torque reference will not be allowed
to exceed this value. Neg Mtr Cur Lim (parameter 73) affects the
minimum value of Neg Torque Lim.

76 Regen Power Lim
Enter the maximum power level that is transferred from the motor
to the DC bus. If you are using an external dynamic brake, you
should set Regen Power Limit to the default level of the drive.
