Installation
The SHA series actuator drives mechanical load system at high accuracy.
When installing the actuator, pay attention to precision and do not tap the actuator output part with a
hammer, etc. The actuator houses an encoder. Excessive impact may damage the encoder.
Installation procedure
1
Align the axis of rotation of the actuator and the
load mechanism precisely.
Note 1: Perform this alignment carefully, especially when
a rigid coupling is used. Even slight
misalignment may cause the permissible load of
the actuator to be exceeded, resulting in
damage to the output shaft.
2
Connect the driver and wiring.
An extension cable is provided. Use it when wiring the driver. For details on wiring, refer to [1-15
Cable specifications].
3
Wire the motor cable and encoder cable.
Do not pull the cables with a strong force. The connection points may be damaged.
Install the
cable with slack not to apply tension to the actuator. Provide a sufficient bending radius (at least
6 times the cable diameter), especially when the cable flexes.
Do not bring strong magnetic objects (magnet chucks, permanent magnets, etc.) near
the rear cover of the actuator. Encoder abnormality may result.
This encoder retains absolute positions when the power is turned OFF by means of
the driver's battery or its own built-in capacitor. If the encoder cable is disconnected for
maintenance, etc., turn on the driver power and charge the backup capacitor first.
After 3 hours of charge, the encoder cable can be disconnected for 30 minutes,
provided that the axis is stopped and ambient temperature is 25
℃
. However, when the
backup capacitor is deteriorated, the absolute positions may not be retained.
Do not disassemble/reassemble the actuator.
May cause damage to electrical and mechanical components.
