1 Detects a time-over and fatal error and decelerates to a stop in deceleration time 1 (See note 1.)
2 Detects a time-over and fatal error and decelerates to a stop in deceleration time 2 (See note 1.)
3 Detects a time-over and nonfatal error warning and continues operating. The warning is

0 0.1 Hz
1 0.01 Hz
2 Converted value based on 30,000 as max. frequency
3 0.1% (Max. frequency: 100%)
Note Communications data after the above conversion is hexadecimal.
For example, if the frequency is 60 Hz and the unit of setting is 0.01 Hz, the converted value is
obtained as follows:
60/0.01 = 6000 = 1770 Hex
H Slave Address (n153)
• Set this parameter to the Slave address (Slave unit number) for communications.
• If more than one Inverter is connected as a Slave, make sure that there will be no Slave address
duplication.
