5.3 Manual operation

The section explains the control input signals to run or control the motor speed at the ON level.
Control input signal : ・Forward command [FWD] (2)
・Reverse command [REV] (3)
・Pulse train ratio 1 (27)
・Pulse train ratio 2 (28)
・Deviation clear (50)
・Multistep speed selection X 1 [X1] (51)
・Multistep speed selection X 2 [X2] (52)
・Multistep speed selection X 3 [X3] (53)
・Acceleration/deceleration
time selection [ACC0] (14)
・Speed command [NREF] (fixed)
5.3.1 Forward command [FWD] / Reverse command [REV]
These signals rotate the motor.
Forward command [FWD] / Reverse command [REV] (Control input signal)
■ Function
While the [FWD] ([REV]) signal is on, the motor rotates forward (in reverse). Acceleration starts at the ON edge, deceleration starts at the
OFF edge.
Simultaneous turning on both [FWD] and [REV], does not stop the motor.
The motor rotates at a speed selected by multistep speed selection [X1], [X2] or [X3].

Basic type (DI/DO) : [NREF] terminal
SX bus type (SX bus direct connection) : IQ area (+10, +11)
T-link type (T-link direct connection) : WB area (+7, +8)
■ Parameter setting
To allocate the [FWD] signal to the control input terminal, set (2) to the system para. (set (3) for the [REV]).
If these signals are not allocated to the control input terminal, these signals are deemed "always off".

(1) Changeover of acceleration/deceleration time
The accel. and decel.(*) time of motor can be set by basic para. 21 to 24. The accel. time and decel. time can be set separetely.
The accel. time is set by the basic para. 21 or 23, regardless of rotational direction.
Note: (*) Accel. : Acceleration, Decel. : Deceleration
