18.5.12 Torque offset
POINT
.
Torque changes steeply depending on the set value in the Torque offset (60B2h)
when the cyclic synchronous mode (csp/csv/cst) switches to the homing mode
(hm), and this may rotate the servo motor. Check the set value in the Torque
offset (60B2h) when switching.
Torque changes steeply depending on the set value in the Torque offset (60B2h)
when servo-on, and this may rotate the servo motor. Check the set value in the
Torque offset (60B2h) when switching.
Torque offset (60B2h) can be used with [Pr. PE47 Torque offset]. When other
than "0" is set to both the parameter and the object, both of the set values in the
Torque offset (60B2h) and [Pr. PE47 Torque offset] are added to the torque
command.
In the test operation mode, the Torque offset (60B2h) is disabled.
(1) Summary
This function compensates the torque command with the set value in the Torque offset (60B2h). This
function will be enabled in the cyclic synchronous mode (csp/csv/cst). The set values will be disabled in
the other control modes.
(2) Usage
(a) Set "_ _ _ 0" or "_ _ _ 1" in [Pr. PA01] and cycle the power of the driver.
(b) Switch the control mode to csp, csv or cst in the Modes of operation (6060h) after the state shifts to
Operational.
(c) Set a value in Torque offset (60B2h).
(3) Monitor data
The following monitor data shows the values to which the set values in Torque offset (60B2h) are added.
