When Command “s” (lowercase letter) is received, the slave side judges that the master side is tripped and operates in accordance with the inter-drive communication parameter (, ).

For detail, see "7. Communication parameters ".

- Examples: 50% frequency command (2-wire RS485 communication)

(If maximum frequency = Frequency for operation at 80Hz = 40Hz: 50% = 5000d = 1388H)
