The built-in regenerative resistor is connected by short-circuiting between the P and D terminals of the 

control circuit terminal block (TE2). (Shipment state). Confirm that a short wire has been connected between 

the P and D terminals.

Disconnect the short wire connected between the P and D terminals, and connect the external option 

regenerative resistor unit P-C between the P and C terminals. The drive unit has an internal regenerative 

resistor electronic thermal (software process), and when overheating of the regenerative resistor is detected, 

an over-regeneration (alarm 30) is detected. The thermal protector terminals (G3, G4) are used when 

double-protecting against overheating of the regenerative resistor. When double-protecting, construct a 

sequence in which an emergency stop occurs if a current stops flowing between G3 and G4.
