Turn off the power and then on again after setting the
parameter to validate the parameter value.
This parameter is supported by a combination of a servo
amplifier, whose software version is C4 or later
(manufactured in January 2010 or later), and a HF-KP
servo motor (manufactured in August 2009 or later).
Check the software version using status display or Setup
software (SETUP221E).
When the 350% maximum torque setting of the HF-KP
servo motor is enabled, set the torque limit value in the
controller at 1000%.
A HF-KP servo motor with a decelerator and servo
motors except the HF-KP series do not support the 350
maximum torque setting. Making the 350 maximum
torque setting valid when using these servo motors
causes the parameter error (37).
Set the control loop composition of the servo amplifier,
and the maximum torque of the HFKP series servo
motor.
By making the high-response control valid in the control
loop composition, response of the servo can be
increased compared to the response under the standard
control (factory setting).Moreover, the track ability for a
command and the settling time in machines with high
rigidity can be decreased. To further shorten the settling
time using the auto tuning results of the high-response
control, increase the setting of model loop gain ([Pr.
PB07]) in the manual mode.
By making the 350 maximum torque setting valid, the
maximum torque of the HF-KP servo motor can be
increased from 300 to 350. To operate at the maximum
torque of 350, operate within the range of overload
protection characteristic. If operated beyond the overload
protection characteristic range, servo motor overheat
(46), overload 1 (50), and overload 2 (51) may occur.
