Communicating with Third-party Devices
The DURAPULSE RJ-12 Serial Comm Port will accommodate an RS-485 connection.
An RS-485 network cable can span up to 1000 meters (4000 feet). The DURA
PULSE
AC drive communication address is specified by P9.00. The third party device
then controls each AC drive according to its communication address.
The DURA
PULSE AC drive can be set up to communicate on standard MODBUS
networks using the following transmission modes: ASCII or RTU. Using the
Communication Protocol parameter (P9.02), you can select the desired mode,
data bits, parity, and stop bits. The mode and serial parameters must be the same
for all devices on a MODBUS network.
