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.
