0: 8, N, 2 (MODBUS, RTU)
1：8，E，1 （MODBUS, RTU)
2：8，O，1 （MODBUS, RTU)
The parameter decide the communication
protocol. Value 8 represents the transmitted data
is 8 bits; N,E,O indicate odd or even:
N: do not use this bit.
E: it represents 1 is even bit.
O: it represents 1 is odd bit.
Value 1 or 2 indicates communication of 1 bit or
2 bits.

Zero-speed
detection
point
1.If the motor running speed is less than the
value of this parameter, the ZSP(zero speed) of
digital output(DO) is ON, or else OFF.
If ZCLAMP of digital input(DI) is ON and speed
command is less than the value of this parameter,
the value of speed command is forced to be zero.
