Axis No. to which torque limit value change request
(S1)
(S2)
(1) The torque limit value of the axis specified with (S1) is changed to the torque limit
value specified with (S2) for the positive direction and negative direction.
(2) In the real mode, any axis that has completed a servo startup can be changed in
torque limit value any time, independently of the status, starting, stopping, servo
ON or servo OFF.
(3) The axis No. that may be set at (S1) is within the following range.
Q173DSCPU
1 to 32
(4) The torque limit value that may be set at (S2) is within the range 1 to 1000[%].
(5) Refer to the "Q173D(S)CPU/Q172D(S)CPU Motion controller (SV13/SV22)
Programming Manual (REAL MODE)" for relation between torque limit value
specified with servo program and torque limit value change instruction.
(1) An operation error will occur and a torque limit value change will not be made if:
• The specified axis No. at (S1) is outside the range; or
• (S2) is an indirectly specified device and its device No. is outside the range.
(2) A minor error will occur and a torque limit value change will not be made if:
• The torque limit value specified with (S2) is outside the range 1 to 1000[%]
(Minor error: 311); or
• The CHGT instruction is executed for any axis that has not yet been started
(Minor error: 312).
