Protection Driver over-temperature protection: 100°C, motor will exit enable mode. Motor over-temperature protection: configurable, recommended ≤90°C, motor will exit enable mode. Over-voltage protection: configurable, recommended ≤54V, motor will exit enable mode. Communication loss protection: if no CAN command is received within the set period, motor will exit enable mode. Over-current protection: configurable, recommended ≤0.98, motor will exit enable mode. Under-voltage protection: motor will exit enable mode if supply voltage falls below set value; supply voltage should not be lower than 20V. Driver over-temperature protection: 100°C, motor will exit enable mode. Motor over-temperature protection: configurable, recommended ≤90°C, motor will exit enable mode. Over-voltage protection: configurable, recommended ≤54V, motor will exit enable mode. Communication loss protection: if no CAN command is received within the set period, motor will exit enable mode. Over-current protection: configurable, recommended ≤0.98, motor will exit enable mode.
