: Refer to Section 5.2 "List of parameters" or Section 5.7 "List of control data" for setting details.
: Torque limit value: Will be an upper limit value of the torque change value. Even if a larger value has been
mistakenly input for the torque change value, it is restricted within the torque limit setting values to prevent an
erroneous entry. (Even if a value larger than the torque limit setting value has been input to the torque change
value, the torque value is not changed.)
: Torque output setting value: to be taken at the start of positioning, and used as a torque limit value. If the value
is "0" or larger than the torque limit setting value, the parameter "torque limit setting value" is taken at the start.
(2) The "torque limit value" set in the Simple Motion module is set in the
PLC CPU
Fig. 13.12 Limiting the torque to the servo amplifier (Axis 1)
parameters shown in the following table, and write them to the Simple
Motion module.
a) The set details are validated at the rising edge (OFF
READY signal [Y0].
Setting
value
Set the torque limit value as a percentage.
[RJ010 mode]
Set the torque limit value after the "[Pr.47] Creep
speed" is reached. Set as a percentage.
[CiA402 mode]
The setting value is ignored.
b) The set details are validated at the rising edge (OFF
positioning start signal [Y10].
Setting
value
Set the torque output value as a percentage.
