CONTROL MODE SELECT
PARAMETER ALLOWABLE RANGE DEFAULT DESCRIPTION
Control Mode Select Enumerated 0 This parameter determines which motor control method will be in
effect when controlling the motor:
0 = Speed Mode Express
1 = Speed Mode
2 = Torque Mode
Consult Curtis for these Control Modes:
3 = Direct Torque Mode (Nm)
1
4 = Simplied Torque Mode
2
5 = Steering Mode
3
6 = PMDC open loop voltage/speed control
7 = Servo Speed Mode
Control_Mode_Select 0 – 7
0x3080 0x00
Use speed and torque modes for either traction or pump motors. e speed modes are typically for
material handling vehicle applications. Torque mode is for on-road vehicle applications.
Note: Tune using the specic control mode, speed or torque, but not both. For example, if adjusting a
torque control parameter while Speed Mode or Speed Mode Express has been selected as the tuning
mode, the (CIT/1313) programmer will show the new setting but it will have no eect.
PMDC open loop voltage/speed control
is is the Motor Technology parameter (0x3534) value 6, PMDC (permanent magnet DC motors).
e diagram illustrates two permanent magnet DC motors connected to the three AC phases UVW.
Consult Curtis and the PMDC supplement manual before proceeding with this control mode.
