Jog operation
The motor runs in one direction at a specified speed as long as the signal is on.
Jog operation is allowed even when homing is not completed.
Set Pr50 – 53,70,71 as follows, and assign the function of signal input.
Of signal inputs 1 – 4,5,7 (
I
1 –
I
6), set the input used for forward jog operation instruction at “4”, and the input used
for reverse jog operation instruction at “5”.
The motor runs in specified direction as long as specified input signal is on.
When the input signal is turned off, the motor reduces its speed and stops.
See Pr4b - 4d for parameters relating to jog operation.
[Timing chart of jog operation]
(1) Change the jog start signal from contact-off to the status of connection to GND (on).
It activates operation.
(2) When the jog start signal is returned to off, the motor starts speed reduction.
(3) When operation is completed, the transistor of in-motion signal (BUSY) returns to off.
･
Operation instruction can be given to the motor only when in-motion signal is off.
･
In jog operation, setting of Pr20 is applied to acceleration and deceleration pattern (linear and S-letter) as for
acceleration. In deceleration, the pattern is linear irrespective of setting of Pr21.
