If the encoder cable or the motor cable is not<br />

connected properly or there is an error with the<br />

position command, this alarm occurs.<br />

Check the connection of the cable and adjust the<br />

electronic gears (SEt-36 and SEt-37).<br />

If the emergency stop circuit is activated, this<br />

alarm occurs.<br />

Clear the emergency stop and cancel the<br />

emergency stop input.<br />

If the input pulse command frequency of the<br />

controller is high, this alarm occurs.<br />

Check the type of the input pulse and the<br />

frequency. It should be 900 kpps or less for the line<br />

drive type and 250 kpps or less for the open<br />

collector type.<br />

If the power is higher than the rated voltage range<br />

(405V), the regenerative resistor is short-circuited,<br />

the regenerative transistor failed, or the operation<br />

exceeds the regenerative capacity, this alarm<br />

occurs.<br />

If the power supply voltage is normal and the load<br />

inertia is not excessive, replace the regenerative<br />

resistor.<br />

If the main power voltage is lower than 200V, this<br />

alarm occurs.<br />

Check the power supply voltage.<br />

If there is an error with the CPU, this alarm will<br />

occur.<br />

If there is an error with the U phase current offset,<br />

this alarm will occur.<br />

If there is an error with the W phase current offset,<br />

this alarm will occur.<br />

If there is an error with the main power supply, this<br />

alarm will occur.<br />
