Communication; Commands And Communication Status - WEG CFW100 Programming Manual

12 COMMUNICATION

In order to exchange information via communication network, the frequency inverter features several standardized
communication protocols, such as Modbus (RTU and TCP), CANopen, DeviceNet, Profibus DP and Ethernet IP.
For further details referring to the inverter configuration to operate in those protocols, refer to the inverter user's
manual for communication with the desired network.

12.1 COMMANDS AND COMMUNICATION STATUS

See below the parameters related to the states and commands through the communication networks available for
the frequency inverter.
P682 - Serial/USB Control
P684 - CO/DN/DP/ETH Control
Range: 0 to FFFF (hexa)
Bit 0 = Ramp Enable
Bit 1 = General Enable
Bit 2 = Run Forward
Bit 3 = JOG Enable
Bit 4 = Remote
Bit 5 = 2nd Ramp
Bit 6 = Reserved
Bit 7 = Fault Reset
Bit 8 to 15 = Reserved
Properties: ro
Description:
The inverter control word for a certain source is accessible for reading and writing, but read only access is permitted
for the other sources. The inverter has a common word for each interface, which is defined by the function of its
bits separately as per Table 12.1 on page
BIT Function
0 Ramp Enable
1 General Enable
2 Run Forward
3 Enable JOG
4 Remote
nd
5 2 Ramp
6 Reserved
7 Fault Reset
8 to 15 Reserved
P683 - Serial/USB Speed Ref.
12-1. The value of P682 is indicated in hexadecimal.
Table 12.1: Status word P682/P684
0: stops the motor by deceleration ramp
1: spins the motor according to the acceleration ramp until reaching the speed reference value
0: disables the inverter completely, interrupting the power supply to the motor
1: enables the inverter completely, allowing the operation of the motor
0: spins the motor in the opposite direction of the reference signal (reverse)
1: spins the motor in the direction of the reference signal (forward)
0: disable JOG function
1: enable JOG function
0: inverter goes into Local mode
1: inverter goes into Remote mode
0: acceleration and deceleration ramp by P100 and P101
1: acceleration and deceleration ramp by P102 and P103
-
0: no function
1: if in fault state, reset the fault
