Parameter Setting
Parameters for Torque Control
5E 0 – 500 % Torque limit • This function limits maximum torque of the motor through setting of
parameters within the driver.
• In normal specifications, torque about 3 times higher than the rated is al-
lowed for an instant. This parameter limits the maximum torque, how-
ever, if the triple torque may cause a trouble in the strength of motor
load (machine).
You cannot set this parameter to a value above a factory setting of the
system parameter (i.e., a factory set parameter that cannot be changed
through of PANATERM
®
and panel manipulation) “Maximum Output
Torque Setting”. A factory setting may vary depending on a combination
of an driver and motor. For further information, refer to “Pr5E Setting of
Torque Limit” of Preparations volume on page 55.
• Setting should be given as a %
value to rated torque.
• The right figure shows a case
in which the maximum torque
is limited to 150%.
• Pr5E limits maximum torque in
both CW and CCW directions
simultaneously.

r/min Zero speed • The parameter directly sets timing to an output zero speed detection out-
put signal (ZSP: CN X5 12-pin) in terms of [r/min].
• A zero speed detection signal (ZSP) is output when motor speed falls
below the speed set with this parameter Pr61.
• Setting of Pr61 acts on both
CW and CCW directions, ir-
respective of the rotating di-
rection of the motor.

r/min At-speed • The parameter sets timing to output a at-speed signal (COIN;CN X5 39-
pin) in speed control and torque control modes in terms of rotational
speed [r/min].
• When the motor speed exceeds setting of this parameter Pr62, at-speed
signal (COIN) will be output.
• Setting of Pr61 acts on both
CW and CCW directions, ir-
respective of the rotating di-
rection of the motor.
