Chapter 4 Communication
NOTE:
Before reading this chapter, make sure you read chapter 3 and understand the installation of
PD-01.
PROFIBUS address
PD-01 has two rotary switches to set the PROFIBUS address, the only way
for user to set the address.
The address switches, ADDH and ADDL, allow user to set the address in a
HEX format. ADDH is used to set high 4 bits of address, and ADDL is used
to set low 4 bits of address. If both ADDH and ADDL are set to F, and PD-01
is power ON or re-power ON, then PD-01 will enter the TEST mode, the SP
LED and NET LED will be in steady orange.
Address Meaning
1..0x7D Valid PROFIBUS address
0 or
0x7E..0xFE
Invalid PROFIBUS address
0xFF Enter TEST mode
NOTE:
Setting changes via address switches will not effective when PD-01 is operating. This means
the setting changes will effective after PD-01 power re-boot. Please understand this cold
restart must be initiated by toggling the power to OFF and then ON.
Parameters setting in VFD series Drives
PD-01 is designed to communicate with VFD series Drives via MODBUS communication port.
Prior to the connection, users have to set parameters below in VFD series Drives:
Set the communication protocol of VFD series Drives to RTU 8, N, 2.
Set the baud rate of VFD series Drives to 9600bps.
Set the frequency source for VFD series Drives to operate via RS485.
Set the operation source of VFD series Drives via MODBUS communication.
Refer to the following table for the above settings when connecting to VFD series Drives:
