Function Explanation
Q1 Q2 • 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 dened
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 coefcient 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 coefcient 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 coefcient in the PID
equation.
Values for # are A, B, C, D, E,
F, G, H or I.
