P0682 - Serial Control Word - WEG bacnet CFW701 User Manual

P0681 = 0000h (0 decimal)

P0681 = 2000h (8192 decimal)

Intermediate or higher speed values in rpm can be obtained by using this scale. E.g. for a 4 pole motor and
1800 rpm of synchronous speed if the value read is 2048 (0800h), then, to obtain the speed in rpm one must
calculate:
8192 => 1800 rpm
2048 => Speed in rpm
Speed in rpm = 1800 × 2048
8192
Speed in rpm = 450 rpm
Negative values in this parameter indicate that the motor is running in the reverse direction.
This parameter is mapped in the ANV16 object.
P0682 – SERIAL CONTROL WORD
Range: 0000h to FFFFh
Properties: -
Access groups via HMI:
Description:
It is the device BACnet interface control word. This parameter can only be changed via serial interface. For the
other sources (HMI, etc.) it behaves like a read-only parameter.
In order to have those commands executed, it is necessary to program the equipment to be controlled via
serial. This programming is achieved by means of parameters P0105 and P0220 to P0228.
Each bit of this word represents a command that can be executed.
