CONTROLLER SETUP — CURRENT LIMITS MENU
PARAMETER ALLOWABLE RANGE DEFAULT DESCRIPTION
Drive Current Limit
Drive_Current_Limit
0x3441 0x00
0 – 100 %
0 – 32767
100 % 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.
Note: Reducing this value will reduce the maximum drive torque.
Regen Current Limit
Regen_Current_Limit
0x3445 0x00
5 – 100 %
0 – 32767
100 % Sets the maximum RMS regen current as a percentage of the
controller's full rated current.
Note: The regen current limit applies during neutral braking direction,
reversal braking, and speed limiting when traveling downhill.
Brake Current Limit
Brake_Current_Limit
0x343C 0x00
5 – 100 %
1638 – 32767
100 % Sets the maximum RMS regen current during braking. The brake
command is the percentage of the controller's full rated current
(100% is maximum current).
Note: 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
0x3443 0x00
5 – 100 %
1638 – 33767
100 % 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
0x3444 0x00
5 – 100 %
1638 – 32767
100 % Sets the maximum RMS regen current during interlock braking as a
percentage of the controller's full rated current.
CONTROLLER SETUP/CURRENT LIMITS — POWER LIMITS MENU
PARAMETER ALLOWABLE RANGE DEFAULT DESCRIPTION
Nominal Speed
PL_Nominal_Speed
0x344E 0x00
100 – 4000 rpm
100 – 4000
1500 rpm Sets the base speed that the drive limiting map and regen limiting
map use.
Delta Speed
PL_Delta_Speed
0x3448 0x00
50 – 1000 rpm
50 – 1000
500 rpm Sets the width of the delta increment that the drive limiting map
and regen limiting map use.
