• 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.
Q1,xx.xx
Q2,xx.xx
• 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.
QD1,xx
QD2,xx
Sets torque derivative to #.
Derivative value # can be any
number from 0 to 99.
QDS1,#
QDS2,#
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.
QI1,xx
QI2,xx
Sets torque integral to #.
Integral value # can be any
number from 0 to 99.
QIS1,#
QIS2,#
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.
QP1,xx
QP2,xx
Sets torque proportional to
# gain.
Proportional gain value # can
be any number from 0 to 99.
QPS1,#
QPS2,#
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.
