Operation of EH-POS in the CPU's stop
Caution 1.Positioner is not applied for CE marking and C-TICK.
2.When the CPU is stopped in the running, the motor goes slow down and stop.
3.Maximum moving distance is 2,147,463,647 pulses in one operation. In case of the over maximum moving distance,
the motion is stopped at the maximum moving value.
4.When a power supply of EH-150 is turned off during a power supply of servo system is on, EH-POS may output some
pulses. So, please turn off the power supply of the servo system, before turning off the power supply of EH-150. And
make homing operation after power supply is turned on in case of position control mode.
