P0682 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.
This bit is mapped in the object BV16
Bit 1
General enable
0: It disables the drive, interrupting the supply for the motor.
1: It enables the drive allowing the motor operation.
This bit is mapped in the object BV17
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.
This bit is mapped in the object BV18
Bit 3
JOG
0: It disables the JOG function.
1: It enables the JOG function.
This bit is mapped in the object BV19
Bit 4
LOC/REM
0: The drive goes to the Local mode.
1: The drive goes to the Remote mode.
This bit is mapped in the object BV20
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.
This bit is mapped in the object BV21
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.
This bit is mapped in the object BV22
Bit 7
Fault reset
0: No function.
1: If in a fault condition, then it executes the reset.
This bit is mapped in the object BV23
Bits 8 to 15
Reserved.

Description:
It allows programming the motor speed reference via the BACnet interface. This parameter can only be changed
via serial interface. For the other sources (HMI, etc.) it behaves like a read-only parameter.
In order that the reference written in this parameter be used, it is necessary that the drive be programmed to
use the speed reference via serial. This programming is achieved by means of parameters P0221 and P0222.
This word uses a 13-bit resolution with signal to represent the motor synchronous speed.
P0683 = 0000h (0 decimal)
→
speed reference = 0
P0683 = 2000h (8192 decimal)
→
speed reference = synchronous speed
Intermediate or higher reference values can be programmed by using this scale. E.g. for a 4 pole 1800 rpm
synchronous speed motor, to obtain a speed reference of 900 rpm one must calculate:
