3 — PROGRAMMABLE PARAMETERS: Control Mode Select Parameter
CONTROL MODE SELECT
ALLOWABLE
PARAMETER RANGE DESCRIPTION
Control Mode Select 0 – 2 This parameter determines which control method will be in effect when
Control_Mode_Select 0 – 2 programming motor response:
0x3010 0x00 0 = speed mode express
1 = speed mode
2 = torque mode.
Contact your Curtis distributor or support engineer if you are interested in
a custom control method.
Note: Do not change this parameter while the controller is powering
the motor. Any time this parameter is changed a Parameter Change Fault
(fault code 49) is set and must be cleared by cycling power; this protects
the controller and the operator.
Note: Motor Speed Constraints
e maximum motor speed is a programmable parameter in each control mode.
Regardless of which control mode is used, the maximum motor speed the controller
will allow is constrained by the number of motor poles, the encoder pulses per motor
revolution, and the maximum speed constraint imposed by the rmware.
Electrical frequency constraint
e controller is designed to output fundamental electrical frequencies
up to 450 Hz. It accomplishes this by clamping the Max Speed allowed,
using the equation
Max Speed Frequency Limit = 54000 / Number of Motor Poles
us, for example, an 8-pole motor running synchronously at 450 Hz
would rotate at 54000/8 = 6730 rpm. erefore the internal control
software will limit the max speed to 6750 rpm for an 8-pole motor.
If the motor were to go over this speed going down a hill, the controller
will still attempt to produce the correct frequency for maximized torque
and proper control; it will not simply clamp to 450 Hz.
Encoder pulses/revolution constraint (quadrature encoder)
e maximum encoder frequency the controller will accept is 10 kHz.
To determine how fast this constraint will allow your motor to spin,
use the equation
MaxSpeedEncoderLimit=600000/EncoderSize
(e.g., a motor with a 128-pulse encoder can run up to 4687 rpm).
Firmware max speed constraint
e maximum motor speed the controller will allow is 8000 rpm.
Max Speed RPM Limit = 8000
e overall maximum motor speed allowed is the least of these three constraints.
is maximum allowed speed is displayed in the
Monitor  Motor  Max Speed
Controller Limit variable.
