CURRENT LIMITS MENU
PARAMETER ALLOWABLE RANGE DESCRIPTION
Drive Current Limit
Drive_Current_Limit
0x305B 0x00
5 – 100%
1638 – 32767
Sets the maximum RMS current the controller will supply to the motor
during drive operation, as a percentage of the controller’s full rated current.*
Reducing this value will reduce the maximum drive torque.
NOTE: Changing this parameter requires the re-setting of the ACIM FW
Base Speed parameter (page 56).
Regen Current Limit
Regen_Current_Limit
0x305C 0x00
5 – 100%
1638 – 32767
Sets the maximum RMS regen current, as a percentage of the controller’s full
rated current.* The regen current limit applies during neutral braking, direction
reversal braking, and speed limiting when traveling downhill.
Brake Current Limit
Brake_Current_Limit
0x305D 0x00
5 – 100%
1638 – 32767
Sets the maximum RMS regen current during braking when a brake command
is given, as a percentage of the controller’s full rated current.* Typically the
brake current limit is set equal to the regen current limit. The brake current
limit overrides the regen current limit when the brake input is active.
EMR Current Limit
EMR_Current_Limit
0x3037 0x00
5 – 100%
1638 – 32767
Sets the maximum RMS current allowed for braking and drive when in
emergency reverse. The emergency reverse current limit is a percentage of
the controller’s full rated current.*
Interlock Brake Current Limit
Interlock_Brake_Current_Limit
0x309D 0x00
5 – 100%
1638 – 32767
Sets the maximum RMS regen current during interlock braking, as a
percentage of the controller’s full rated current.*
* The full rated current depends on the controller model;
see specications in Table D-1 for the rated current of your model.
POWER LIMITING MAP MENU
PARAMETER ALLOWABLE RANGE DESCRIPTION
PL Nominal Speed
PL_Nominal_Speed
0x305E 0x00
100 – 4000 rpm
100 – 4000
Sets the base speed that will be used in the drive limiting map and regen
limiting map.
NOTE: Changing this parameter requires the re-setting of the ACIM FW
Base Speed parameter (page 56).
Delta Speed
PL_Delta_Speed
0x305F 0x00
50 – 1000 rpm
50 – 1000
Sets the width of the delta increment that will be used in the drive limiting
map and regen limiting map.
