Torque-Related Constants; Sequence-Related Constants - YASKAWA SGM Series User Manual

7.1.2 Torque-related Constants

The following torque-related user constants are available.
J Cn-0006: Emergency Stop Torque
D Sets the stopping torque (deceleration by emergency stop torque with deceleration constant
Cn-0001 bit 8 set to 1) for overtravel.
D Allowable setting range: 0 to maximum torque [%]
J Cn-0008: Forward Torque Limit
D Sets the motor torque limit for forward rotation (for reverse rotation with reverse rotation
mode).
D The motor torque will be controlled within this limit during forward rotation.
D Allowable setting range: 0 to maximum torque [%]
J Cn-0009: Reverse Torque Limit
D Sets the motor torque limit for reverse rotation.
D The motor torque will be controlled within this limit during reverse rotation.
D Allowable setting range: 0 to maximum torque [%]
J Cn-0017: Torque Reference Filter Time Constant
D Sets a primary lag filter to add to the reference torque for speed error and speed loop gain.
D This constant is used to prevent vibration due to mechanical resonance.
D Allowable setting range: 0 to 25000 [µs]
J Cn-0018: Torque Reference Filter Time Constant (Secondary)
D Sets a secondary lag filter. The filtering effect can be improved by applying a secondary lag
filter to the reference torque.
D Specifying a value other than 0 applies a secondary lag filter.
D Allowable setting range: 0 to 25000 [µs]

7.1.3 Sequence-related Constants

The following sequence-related user constants are available.
J Cn-0012: Time Delay from Brake Reference to Servo OFF
D Sets the time delay from the brake reference output to Servo OFF when a Servomotor with
a brake is used.
D Allowable setting range: 0 to 50 [× 10 ms]
