Moves further beyond origin.
[LS] may not be turned on/off. Use 3-wire type of [LS] or contact output.
Stop position different by one
rotation of motor-shaft
Speed reduction ratio excessive
Z-phase of encoder is near FF edge of [LS]. Mechanical move the
position. Stop position can be adjusted by origin shift of basic para.
Pulse count until Z-phase is detected from OFF edge can be displayed
by touch panel : On011.
Stops at position set by basic
para. 79.
Check for erroneous motion of [LS], distance of proximity switch.
Move the [LS] position opposite to return direction. Move the [LS] to
increase the origin shift.
Moves past the origin and then
returns.
When required, replace the [LS] with optical detector or other quick
responding device.
In mechanical positioning,
gear ratio has fractional No.
If gear ratio is 1/2.5, machine and Z-phase match after 5 shaft rotation.
For positioning a rotating equipment, apply RYS-R type amplifier.
Origin return action is ineffective. [ORG] may be turned on at all times after turning on power.
