NOTE!
The values transmitted over the network have a scale limitation, allowing a maximum of 4 times the
synchronous speed of the motor, with saturation in 32767 (or -32768).
P0684 – DEVICENET CONTROL WORD
Range: 0000h a FFFFh Default: 0000h
Properties: NET
Access groups via HMI: NET
Description:
It is the device DeviceNet interface control word. This parameter can only be changed via
CANopen/DeviceNet/Profibus DP 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
CANopen/DeviceNet/Profibus DP. 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.

Table 4.3: P0684 parameter bit functions
Bits Values
Bit 0
Run/Stop
0: It stops the motor with deceleration ramp.
1: The motor runs according to the acceleration ramp until reaching the speed reference value.
Bit 1
General enable
0: It disables the drive, interrupting the supply for the motor.
1: It enables the drive allowing the motor operation.
Bit 2
Speed direction
0: To run the motor in a direction opposed to the speed reference.
1: To run the motor in the direction indicated by the speed reference.
Bit 3
JOG
0: It disables the JOG function.
1: It enables the JOG function.
Bit 4
LOC/REM
0: The drive goes to the Local mode.
1: The drive goes to the Remote mode.
Bit 5
Second ramp
0: The drive uses the first ramp values, programmed in P0100 and P0101, as the motor acceleration
and deceleration ramp times.
1: The drive is configured to use the second ramp values, programmed in P0102 and P0103, as the
motor acceleration and deceleration ramp times.
Bit 6
Quick stop
0: It does not execute the quick stop command.
1: It executes the quick stop command.
Note: This function is not allowed with control types (P0202) V/f or VVW.
Bit 7
Fault reset
0: No function.
1: If in a fault condition, then it executes the reset.
Bits 8 to 15 Reserved.
P0685 – DEVICENET SPEED REFERENCE
Range: -32768 to 32767 Default: 0
Properties: NET
Access groups via HMI: NET
Description:
It allows programming the motor speed reference via the DeviceNet interface. This parameter can only be
changed via CANopen/DeviceNet/Profibus DP interface. For the other sources (HMI, etc.) it behaves like a read-
only parameter.
