AC70 VC CONTROL FREQUENCY INVERTER MANUAL
FUNCTION PARAMETER DETAILED SPECIFICATION
117
H-66 Linkage main station setting
Range: 0,1,2
Default: 0
0: Local machine configure as linkage slave station
1: Main station control mode 1. Sent frequency reference and running command of main inverter to slave inverter.
2: Main station control mode 2. Sent output frequency and running command of main inverter to slave inverter.
When this frequency configure for main station, it has linking control function, enable to control other AC70 inverter
of network synchronous running.
H-67 Local inverter address
Range: 1-247
Default: 1
Uses to define communication address of local machine when it has been set for slave one. It makes no sense if it
is set for main inverter.
H-68 Data format
Range: 0,1,2,3
Default: 3
0: (N,8,1), no check, data bit: 8, stop bit: 1
1: (E,8,1), even parity check, data bit: 8, stop bit: 1
2: (0,8,1), odd parity check, data bit: 8, stop bit: 1
3: (0,8,2), no check, data bit: 8, stop bit: 2
H-69
Baud rate
Range:0- 5
Default:3
0:1200bps
1:2400bps
2:4800bps
3:9600bps
4:19200bps
5:38400bps
H-70
Communication setting
frequency ratio
Range:0.01-5.00
Default:1.00
Take frequency reference from upper controller multiply this parameter for this machine frequency reference.
Modification with proportional scale for given frequency from upper controller is available.
H-71
Time of communication time
out
Range:0.0-6500.0s
Default:10.0s
If the interval time between a communication and the next communication exceeds communication overtime time, it
is considered there is communication disconnection fault, malfunction disconnection action mode is decided by the
[H-72].
H-72
RS485 communication
broken responding mode
Range:0-2 Default:
1
LED“0” digit: RS485 communication broken responding mode
0: giving alarm and free stop When the inverter setting given communication command don’t receive next
frame command or any other communication command respond over
[H-17]
given time, inverter will giving alarm
and free stop .
1: No alarm and continue running Inverter don’t make any fault detect, continue running with last communication
