Note 1: If main circuit voltage is less than 170V/330V(for 220V/400V series), the
undervoltage fault occurs and the electrical level of the servo fault (ALM) output increases.
Note 2: If the drive temperature is less than 45 ° C, the fan stops. If the IGBT temperature is
higher than 45 ° C, the fan stops after the microprocessor stops.
Note 3: The output delay of the electromagnetic brake release signal can be set through
P3.57. If the speed slows down under the setting of P3.58 (30r/min by default) during the
time specified by P3.57, the BRK signal becomes invalid.
Note 4: The actual electrical levels corresponding to valid I/O states can be set through
P3.00–P3.15.
