~~~
1. The AD71 will wait until the output speed is zero before giving a second jog
output.
Fig. 6.8 Jog Repetition
2. Interpolation is not enabled during jog operation.
3. The AD71 defaults to forward jog if both forward and reverse jog corn.
mands are given simultaneously.
6.3.5 Inching
The operating principle for the manual pulser inching function is
described below:
1) When the manual pulser instruction is given the inching signal is
transmitted to the AD71.
2) The number of manual pulses is converted into output pulses
according to the following expression:
Number of output pulses to drive = p
RxQ
where P = "travel per pulse" in the parameters
0 = "travel per inching input" in the parameters
R = number of manual pulses
3) The output pulses are fed to the motor drive unit.
0 Pulse output speed is fixed at 20KPLS/sec and is not under
acceleration/deceleration control. Hence, if the inching speed
is too high, the drive unit cannot keep up. In this case, set the
travel per pulse to a smaller value.
4) The BUSY signal for the relevant axis is on during inching.
