12 CONTROL AUXILIARY FUNCTIONS
(2) Precautions during control
(a) If a value other than "0" is set in the "
Cd.30 New torque value", the torque
generated by the servomotor will be limited by that value. To limit the torque
with the value set in "
Cd.101
Torque output setting value", set "0" in the
"
Cd.30 New torque value".
To limit the torque with the value set in "
Pr.18
Torque limit setting value",
set "0" in the "
Cd.101
Torque output setting value" and " Cd.30 New torque
value".
(b) The "
Cd.30 New torque value" is validated when it is written to the
AD75.However, there is a maximum delay of 56.8ms from when the new
torque value is written until the torque is limited with the new value.
(c) At a start of the corresponding control, the "
Cd.30
New torque value" is
cleared to "0", and the torque is limited with the "
Cd.101
Torque output
setting value".
(d) If the setting value is outside the setting range, a warning "Outside torque
change value range" (warning code: 113) will occur and the torque will not
be changed.
(3) Setting the torque change function start signal
To use the "torque change function", write the data shown in the following table
to the AD75 using the sequence program.
The set details are validated when written to the AD75.
