P0681 – MOTOR SPEED IN 13 BITS
Range: - 32768 to 32767 Default: -
Properties: RO
Access groups 01 PARAMETER GROUPS
via HMI:
∟
49 Communication
∟
111 Status / Commands
Description:
It allows monitoring the motor speed. This word uses 13-bit resolution with signal to represent the motor
synchronous speed:

P0681 = 0000h (0 decimal) → motor speed = 0

P0681 = 2000h (8192 decimal) → motor speed = synchronous speed
Intermediate or higher speed values in rpm can be obtained by using this scale. E.g. for a 4 pole 1800 rpm
synchronous speed motor, 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 ANV28 object.
P0682 – SERIAL CONTROL WORD
Range: 0000h a FFFFh Default: 0000h
Properties: NET
Access groups 01 PARAMETER GROUPS
via HMI:
∟
49 Communication
∟
111 Status and commands
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.
