Parameters for Torque Limits
PrNo. Parameter Name Function/Content
• With this parameter set, maximum torque of the motor is limited in the driver.
• Normal specification allows torque about 3 times as large as rated torque, if in an
instant. We recommend that you limit the maximum torque with this parameter if the
tripled torque might cause trouble to intensity of the motor load (machine).

• You can give setting as a percentage
(%) value to rated torque.
• The right figure shows an example in
which it is limited to 150%.
• Pr5E limits the maximum torque of
both CW and CCW directions simulta-
neously.

<Remarks>
With torque limit switching function enabled (Pr06=2), this parameter is a
value of the 1st torque limit.
<Cautions>
You cannot set to this parameter a value that exceeds a default setup value with
“Maximum Output Torque Setting” of the system parameter (i.e., factory default
parameters that cannot be changed through manipulation of PANATERM
® and
console). A default may differ depending on a combination of a motor and driver. For
detailed information, refer to “Setting of 1st Torque Limit” on Page 45 of Preparation
edition.

PrNo. Parameter Name Function/Content
• The parameter directly sets in [r/min] timing to output zero speed detection
output signal (WARN: CN X5 pin 12).
You need to set parameter warning output selection (Pr09) to 1.
• The zero speed detection signal (WARN) will be output when the motor speed
falls below the set speed of this parameter Pr61.
• In internal velocity control mode, the parameter sets timing to output achieved
speed signal (COIN: CN X5 pin 10) with rotation speed [r/min].
• The achieved speed signal will be output when the motor speed exceeds the
speed set by this parameter Pr62.

• Setting of Pr61 acts on both CW and
CCW directions, irrespective of the
direction of motor rotation.
• There is hysteresis of 10 rpm. Set the
parameter 10 or more.
