X3 X2 X1 Rotation speed
OFF OFF OFF Speed command (VREF terminal) voltage
OFF OFF ON PA1_41: Manual feed speed 1
OFF ON OFF PA1_42: Manual feed speed 2
ON ON ON PA1_43: Manual feed speed 3
ON OFF OFF PA1_44: Manual feed speed 4
ON OFF ON PA1_45: Manual feed speed 5
ON ON OFF PA1_46: Manual feed speed 6
ON ON ON PA1_47: Manual feed speed 7
(2) Position control
In the position control mode, only pulse inputs are accepted.
To perform manual operation under position control, specify "6" (extension mode) or "7"
(positioning operation) to PA1_01 (control mode selection) and, while leaving the position control
(37) signal turned on (not necessary when "7" (positioning operation) is set to PA1_01), turn on
the forward command [FWD] (or reverse command [REV]) signal.
The speed setting is the same as that of speed control. The rising edge of the forward command
[FWD] (or reverse command [REV]) signal starts to rotate at the ON level. Even if both signals are
turned on simultaneously, no stoppage is caused.
To issue a reverse command after turning off a forward command [FWD], turn on the reverse
command [REV] after controlled stop.
(3) Torque control
A torque is output at the servomotor shaft.
The torque is output according to the torque command [TREF terminal] voltage.
Parameter setting
To assign the forward command [FWD] signal to a sequence input terminal, specify the
corresponding value ("2"; "3" for reverse command) to the input terminal function setting
parameter.
