Torque limit value change request: CHGT
Format Setting data Contents Result data type
(S1) Axis No. to request for torque limit value change
CHGT ((S1), (S2))
(S2) Designated torque limit value
–
(1) The torque limit value of the axis designated by (S1) is changed to the torque limit
value designated by (S2).
(2) If the servo has been started for the axis in the real mode, the torque limit value
can be changed regardless of whether operation has been started or stopped, or
whether the servo is ON or OFF.
(3) The range of axis numbers set in (S1) is shown below.
Q172CPU Q173CPU
1 to 8 1 to 32
(4) The range of torque limit value that can be set in (S2) is 1 to 500 [%].
(5) The relation of the torque limit value and torque limit value designated by the
servo program is shown below.
At start
The torque limit value is commanded to the servo of the start axis according to the
"P. torque" set with the servo program or the "torque limit value" in the designated
parameter block.
When interpolation is started, the torque value is limited for the interpolation axis.
↓
When the CHGT command is executed, the setting torque limit value is
commanded only to the designated axis.
↓
The torque limit value commanded to the servo when starting the servo program
or when starting JOG is valid thereafter only when it is less than the torque limit
value changed by CHGT.
This torque limit value is clamped for each axis.
During start
1) Even when the following setting is made, the torque limit value is not
changed to the torque limit value higher than that changed by the
CHGT command.
• Torque limit value at halfway point during constant speed control or
speed change control
• Torque limit value when speed/position changeover control is
changed to position control
• Torque limit value in speed control II
2) It is possible for CHGT command to change the torque limit value to a
value higher than the torque limit value set by the servo program or
parameter block.
