REMARKS

*1 The "starting frequency" in Pr. 13 (factory-set to 0.5Hz) may be set between 0 and 60Hz.

*2. If the next start signal is given during DC injection brake operation, the DC injection brake is disabled and restart is made.

*3. The "DC injection brake operation time" in Pr. 11 (factory-set to 0.5s) may be set between 0 and 10s.

*4. The frequency at which the motor is coasted to a stop is not more than the "DC injection brake operation frequency" set in Pr. 10 (factory setting = 3Hz; may be set between 0 and 120Hz) or not more than 0.5Hz.

*5. The "starting frequency" in Pr. 13, "DC injection brake operation time" in Pr. 11 and "DC injection brake operation frequency" in Pr. 10 are the factory-set values.
