Multi-Step Speed Selection [X1]: Sequence Input Signal (Reference Value 51); Multi-Step Speed Selection [X2]: Sequence Input Signal (Reference Value 52); Multi-Step Speed Selection [X3]: Sequence Input Signal (Reference Value 53) - Fuji Electric Alpha7 VV User Manual

Multi-step speed selection [X1]: Sequence input signal (Reference value 51)

Multi-step speed selection [X2]: Sequence input signal (Reference value 52)

Multi-step speed selection [X3]: Sequence input signal (Reference value 53)

Select the manual feed speed when in position control mode or speed control mode. This is used to
select the speed limit value when in torque control mode.
 Function
The rotation speed while the forward command [FWD] (reverse command [REV]) signal is turned
on is selected.
When in torque control mode, the servomotor rotation speed is limited to the selected speed.
Select the speed with multi-step speed [X1], [X2] or [X3].
