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].
The setting speed is shown in the table below.
X3 X2 X1
Parameter
No.

OFF OFF OFF - Speed command terminal (VREF) voltage
OFF OFF ON PA1_41 Manual feed speed 1/torque control speed limit 1
OFF ON OFF PA1_42 Manual feed speed 2/torque control speed limit 2
OFF ON ON PA1_43 Manual feed speed 3/torque control speed limit 3
ON OFF OFF PA1_44 Manual feed speed 4/torque control speed limit 4
ON OFF ON PA1_45 Manual feed speed 5/torque control speed limit 5
ON ON OFF PA1_46 Manual feed speed 6/torque control speed limit 6
ON ON ON PA1_47 Manual feed speed 7/torque control speed limit 7
 Parameter setting
To assign the multi-step speed selection to a sequence input terminal, specify the corresponding
value ("51", "52" and "53") to the input terminal function setting parameter.
These signals are handled to be always turned off if they are not assigned to sequence input
terminals.
