Chapter 7 Motion Control Functions
Function of Clutch
Lead Pulse Number
(Monitoring Variable
061)
When the direction of lead pulse is not set correctly, it will cause
that the value of the monitoring variable 061 becomes higher
and higher and finally lead to overflow. At this time, E-Cam
function will be disabled (P5-88 X=0) and the status of E-Cam will
be forced to be changed to Stop.
Disengaging Timing
(P5-88 U Settings)
This option is used to determine the disengaging timing when the
status of E-Cam is Engaged.
Please note that the condition 2, 4, and 6 are mutually exclusive;
that is, only one of them can be selected.

(This setting is only available in
firmware V1.009 and later models)
Fixed number of master pulses (P5-

The function is the same as the
setting of U=2. The difference is that
the speed will not change when
disengaging and the engaging length
will exceed the setting value of P5-89
a little. This setting is suitable for
the application which needs to use
PR command immediately when
disengaging.
