• Error includes Light failure error and Heavy failure error.
• If light failure error occurs, the positioning operation will continue and only error will occur.
• In case of heavy failure error, if the error is not cleared, it is not available to carry out the positioning operation. And if the
heavy failure error occurs during operation, the operation will stop.
• If external high/low limit, external emergency stop during the positioning operation are detected during the positioning
operation, it stops promptly and becomes the pulse output prohibition status. Thus it is required to release the pulse
output prohibition by Error reset command(POSCTR)
