OPERATION
8.6.5 SpeeD CoMManDS
Command
Code
Function Explanation
F# Sets maximum speed to # rpm. Sets a speed range for the Controller. Must
be specified before using the speed or ramp
mode.
G# Sets maximum speed excited
of PB.
Range is 0 to 10,000.
N • Resets speed point to
maximum speed.
• Sets speed mode OFF.
• Sets brake OFF.
Use this command, sent alone, to reset
any previous speed-stabilized setting to the
maximum speed range.
N# • Sets speed point to #.
• Sets brake ON.
Use this command to load the motor under
test to a specific speed value #. Issue a speed
range command (F#) first for best dynamic
response. The Controller is functioning with the
dynamometer as a closed loop system. Adjust
the speed PID values to tune the response.
ND# Sets speed derivative to #. Derivative value # can be any number from 0
to 99.
NDS# Used as a multiplier for the D
coefficient in the PID equation.
Values for # are A, B, C, D, E, F, G, H or I. (See
Appendix F: Additional Scale Factor Table.)
NI# Sets speed integral to #. Integral value # can be any number from 0 to
99.
NIS# Used as a multiplier for the I
coefficient in the PID equation.
Values for # are A, B, C, D, E, F, G, H or I. (See
Appendix F: Additional Scale Factor Table.)
NP# Sets speed proportional to #
gain.
Proportional gain value # can be any number
from 0 to 99.
NPS# Used as a multiplier for the P
coefficient in the PID equation.
Values for # are A, B, C, D, E, F, G, H or I. (See
Appendix F: Additional Scale Factor Table.)
8.6.6 torqUe CoMManDS
Command
Code
Function Explanation
Q • Resets torque to 0.0.
• Turns torque mode OFF.
• Turns brake OFF.
This command resets any previous torque-
stabilized command, and returns the motor to
free run.
Q# • Sets torque point to #.
• Turns brake ON.
This is a closed loop command with its own set
of PID parameters. The units defined will be
the same as those displayed by the Controller.
QD# Sets torque derivative to #. Derivative value # can be any number from 0
to 99.
QDS# Used as a multiplier for the D
coefficient in the PID equation.
Values for # are A, B, C, D, E, F, G, H or I. (See
Appendix F: Additional Scale Factor Table.)
QI# Sets torque integral to #. Integral value # can be any number from 0 to
99.
QIS# Used as a multiplier for the I
coefficient in the PID equation.
Values for # are A, B, C, D, E, F, G, H or I. (See
Appendix F: Additional Scale Factor Table.)
QP# Sets torque proportional to #
gain.
Proportional gain value # can be any number
from 0 to 99.
QPS# Used as a multiplier for the P
coefficient in the PID equation.
Values for # are A, B, C, D, E, F, G, H or I. (See
Appendix F: Additional Scale Factor Table.)
