Overview
HG-RR153 is a 1.5kW ultra-low inertia, high-response AC servo motor of the MELSERVO-J4 series. It has a high dynamic response, medium power, and high-precision servo drive unit. It is suitable for fast start and stop, and high-frequency reciprocating action equipment. The rotor inertia is only 1.9 kg·cm², and it accelerates and decelerates very quickly, enabling millisecond-level start, stop, and reversal. It comes standard with a 22-bit absolute encoder, with a single-turn resolution of 4.19 million pulses.

FAQ:
1.Which Mitsubishi servo driver is the HG-RR153 compatible with?
Pulse type: MR-J4-200A / MR-J4-200A4
Bus type: MR-J4-200B / MR-J4-200B4
2.What are the common reasons for an overload alarm on HG-RR153?
- Excessive mechanical load, stuck or abnormal resistance
- The acceleration and deceleration time is set too short and starts and stops frequently.
- Torque limit parameter set too low
- Motor and driver power do not match
- The transmission mechanism has large clearance, eccentricity or inconsistent installation.
- The motor has poor heat dissipation and the ambient temperature is too high.
- Encoder exception or parameter setting error
3.What is the difference between HG-RR153 and HG-RR153B?
The only difference between HG-RR153 and HG-RR153B is whether it has electromagnetic braking.
- HG-RR153: No electromagnetic brake
- HG-RR153B: With electromagnetic power-off braking (brake), it automatically locks the shaft when power is off to prevent falling.
