Serial - WEG CFW100 Programming Manual

COMMUNICATION
P685 - CO/DN/DP/ETH Speed Ref
Range:
Properties:
Description:
It allows programming the motor speed reference via communication interfaces only. For other sources (HMI, etc.),
it behaves as a read-only parameter.
To enable the use of the reference written in this parameter, the product must be programmed to use the speed
reference via communication network. This is programming is done using parameters P221 and P222.
This word uses a 13-bit resolution with signal to represent the motor rated frequency (P403):
P683 = 0000h (0 decimal) → speed reference = 0.
P683 = 2000h (8192 decimal) → speed reference = rated frequency (P403).
P685 = 0000h (0 decimal) → speed reference = 0.
P685 = 2000h (8192 decimal) → speed reference = rated frequency (P403).
For a detailed description, refer to the user manual of the communication network, available for download on the
