SP9057 Excessive Deceleration Power

An overload was detected in the regenerative resistance (PSMR alarm indication: 08). Thermostat operation or short-time overload was detected. The regenerative resistor was disconnected or an abnormal resistance was detected. Decrease the acc/dec duty. Check the cooling conditions (peripheral temperature). If the cooling fan stops, replace the resistor. If the resistance is abnormal, replace the resistor.

Quick tip:

Check regenerative resistance
