Description
0.0s(disabled)～60.0s(works for master-
slave system) When this function code
effective, if slave do not receive data
from master overtime, it will trip as
Er.485
Each time a frame is received, this value
is incremented by 1,0 to 65535 cycles.
Each time a frame is sent, this value is
incremented by 1,0 to 65,536 cycles.
Each time an CRC error frame is
received, this value is incremented by
1,0 to 65535 cycles; it can be used to
judge the degree of communication
interference.
0: Slave
1: Master(sent by broadcast )
1～9 corresponds to 0x7001～0x7009
0:output frequency
1:set frequency
2:output torque
3:set torque
4:PID setting
5:PID feedback
6:output current
0.010～10.000sAs a master, after
sending one frame of data, the next
frame of data is sent after this delay.
-10.000～10.000The values of slave
registers 0x7001 and 0x7002 take
effect after passing through this scaling
factor
0: 0.01%
1: 0.01Hz
2: 1Rpm
Some units of specific communication
registers can be set by this parameter.
See Appendix A for details.
When the format of the received frame is
a write register, this parameter can be
set to reply to the host.
0: Reply to the host (standard Modbus
protocol)
1: Do not reply to the host (non-standard
Modbus protocol)
