Torque Limits
Section 10-4
The SMARTSTEP Junior Servo Drives do not support torque control. The fol-
lowing settings and functions cannot be used.
10-4-2 Constant Torque Limits
G5-series Servo Drives
To apply a constant torque limit to axis operation, set the Servo Parameters
No.1 Torque Limit
(Pn013) and
No.2 Torque Limit
(Pn522). By setting these
parameters, the output torque of the operating Servomotor will always be lim-
ited by the set ratio of the rated torque. Also by setting the
Torque Limit Selec-
tion
(Pn521), the forward torque limit and reverse torque limit will be as shown
in the following table.
Torque Limit Parameters
G-series Servo Drives
To apply a constant torque limit to axis operation, set the Servo Parameters
No.1 Torque Limit
(Pn05E) and
No.2 Torque Limit
(Pn05F). By setting these
parameters, the output torque of the operating Servomotor will always be lim-
ited by the set ratio of the rated torque. Also by setting the
Torque Limit Selec-
tion
(Pn003), the forward torque limit and reverse torque limit will be as shown
in the following table.
Torque Limit Parameters
W-series Servo Drives
To apply constant torque limits to axis operation, set the Servo Parameters
Forward Torque Limit
(Pn402) and
Reverse Torque Limit
(Pn403). By setting
this parameter, the output torque of the operating Servomotor will always be
limited by the set ratio of the rated torque.
