Omron V1000
Connected via RS485:
 R+ is connected to S+
 R- is connected to S-
 R+/S+ is connected to B on port 1 or 2
 R-/S- is connected to A on port 1 or 2
Parameters
The following parameters must be set from the display of the frequency converter:
 H5-01 (0x425): Slave address, set to = 1 for Supply air fan and = 2 for Exhaust air fan
 H5-07 (0x42B): RTS Control, set to = 1 (enabled) for activation of RS485
 o1-03 (0x502): Frequency reference units, set to = 1 for 0-100%.
 H5-03 (0x427): Parity, set to = 0 (no parity)
Default values should be used for remaining parameters. The following values may not be changed:
 H5-02 (0x426): Communication speed, default =3 (9600)
 H5-04 (0x428): Stopping method after communication error, default = 3 (no stop)
 H5-11 (0x43C): Communication Enter Function, default=1 (Enter command not
necessary)
 H5-12 (0x43D): Run command, default=0 (bit 0=forward start/stop, bit 1= reverse
start/stop)
 b1-01 (0x180): Frequency Reference selection 1, default = 2 (via Modbus)
 b2-01 (0x181): Run command selection 1, default = 2 (via Modbus)
