Sub-Mode Display - Fuji Electric Faldic-a RYS-R Series User Manual

(ii) Sub-mode display
(*1) Displays the current present status
Indication Description
In base-off condition, the motor has no driving force
and in free-run status.
The motor can rotate and is waiting the run
command.
The motor can rotate and is executing manual feed.
The motor can rotate and the pulse train input is valid.
The motor can rotate and is executing positioning
operation.
The motor can rotate and is executing origin return.
The motor can rotate and is executing interrupt
positioning.
The amplifier is executing deviation clear.
The motor can rotate and is measuring the brake
timing.
The motor is stopping with positioning cancel signal.
(b) Motor hunting rotation (motor shaft rotates forward/reverse repeatedly)
The amplifier which incorporates a real-time turning function estimates the mechanical equipment system at all times. For the amplifier, the
real-time turning function is factory validated.
The real-time turning function is valid for most mechanical equipment systems except some examples. If it does not work, contact us.
Motor hunting
Check the connection of motor
power to U, V, W of amplifier.
If mechanical equipment system
and motor are disconnected, still
hunting occurs ?

Check and remedy
Turn on the run command [RUN].
Turn off the free-run command [BX].
Manual forward [FWD] may not be valid.
The motor is already rotating.
Increase the analog input voltage or multistep speed setting.
The pulse train may not be input or the pulse train signal form
may be different.
Increase the speed data.
Increase the origin creep speed.
−
