Warning
Consider possible unexpected movements of the Card Motor in the event of an emergency
stop, alarm or power failure.
If power is not supplied to the Card Motor due to an emergency stop, if the SVON signal is
switched OFF, in the event of an alarm (when the temperature of the Card Motor exceeds 70
o
C)
or at power failure, the table will not be held in place and may be moved by external forces. If
the Card Motor is mounted vertically or at a slant, the table will drop.
Design the Card Motor application so that people and equipment will not be injured or damaged
by the table movement.
Caution
Do not hit the stroke ends with the work piece in operations other than return to Origin
position or at speeds higher than the pushing speed during pushing operation.
The Card Motor is equipped with a stopper to prevent the table from coming off and to be
resistant to the light impacts generated when returning to Origin position and when transferring
work pieces within the specified limits. Excessive external force or impact may damage the Card
Motor.
Install a separate external stopper if the operating conditions require.
For pushing operations, set the target position at least 1 mm away from the position where the
table or the pushing tool comes into contact with the work piece.
Otherwise, the table may hit the work piece at a speed exceeding the specified 6 mm/s pushing
speed, which could damage the work piece and the Card Motor.
The Card Motor must not overheat.
The temperature rise of the Card Motor depends on the ambient conditions and usage. Take the
following countermeasures if the temperature of the Card Motor rises so high that a temperature
alarm is generated:
-
Reduce the thrust force setting value.
-
Reduce the duty ratio by increasing the cycle time.
-
Improve the heat transfer properties of the mounting base and the surroundings.
Refer to section “8. Alarm detection” (P.60) for details.
The thrust force generated by the Card Motor varies in relation to the ”Thrust Setting Value”,
depending on the table position, pushing direction and operating environment.
The ”Thrust Setting Value” in the step data is a nominal value. Therefore please calibrate
the ”Thrust Setting Value” according to the application under real conditions.
