5 OPERATION CONTROL PROGRAMS
[Errors]
[Program examples]
(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) or (S3) 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) or (S3) is outside the range of 0.1 to
1000.0[%] (Minor error: 311); or
• The CHGT2 instruction is executed for any axis that has not yet been started
(Minor error: 312); or
• When the CHGT2 instruction is executed for any axis during speed-torque
control, the value of (S2) or (S3) is greater than the torque limit value in speed-
torque control (Minor error: 319); or
• In the virtual mode, the CHGT2 instruction is executed for any axis that the
torque limit value of output module is indirectly specified with a device (Minor
error: 6260).
(1) Program which changes the torque limit value of axis 2 to positive direction
20.0[%] and to negative direction 10.0[%]
CHGT2(K2, K200, K100)
POINT
There will be a delay of time equivalent to an operation cycle at the maximum in the
time from when the CHGT instruction is executed until the torque limit value is
transferred to servo amplifier actually.
