Torque Limit 0: Sequence Input Signal (Reference Value 19); Torque Limit 1: Sequence Input Signal (Reference Value 20) - Fuji Electric ALPHA7 User Manual

CHAPTER 2 WIRING

Torque limit 0: Sequence input signal (Reference value 19)

Torque limit 1: Sequence input signal (Reference value 20)

Limitations are set on the output torque of the servomotor.
The torque limit 0 signal is enabled only for VS type.
2
 Function
Limitation on the output torque of the servomotor by turning on the torque limit signal can be set.
Specify the torque limit in increments of 1 [%] in the range from "0" to the maximum output torque.
The maximum output torque is 300 [%] if the rated torque is 100 [%].
Note that the setting of PA1_37 to 40 (acceleration and deceleration time) may be ineffective if the
output torque is limited during acceleration or deceleration. The enabled torque limit is as follows.
VS type: The torque limit function is always enabled in all control modes.
 Torque limit under speed control and position control
The following settings can be specified as a limitation set on the torque.
[1] IQ area (4000H/300 [%])
[2]
Forward rotation torque limit (PA1_27), reverse rotation torque limit (PA1_28)
[3]
Second torque limit (PA2_58)
[4]
Third torque limit (PA2_60)
If "0" is specified as torque limit selection (PA2_57), the settings of torque limit 0 and torque limit 1
are enabled. Only torque limit 1 is enabled for LS type.

If forced stop or servo-on is turned off, or if an over-travel or minor failure alarm is detected,
limitation is set at [4] third torque limit (PA2_62＝4 or 5 or 20□□) the setting can be changed.
