COMMAND AND REFERENCES
P225 - LOC JOG Selection
P228 - REM JOG Selection
Range:
Properties:
Description:
They define the origin source for the JOG function in the Local and Remote situation. The JOG function means a
Run/Stop command added to the reference defined by P122. Refer to
7-6.
P229 - Stop Mode Selection
Range:
Properties:
7
Description:
This parameter defines the motor stop mode when the inverter receives the "Stop" command.
7-6 describes the options of this parameter.
✓
NOTE!
When the Coast Stop mode is programmed and the Flying Start function is disabled, only activate
the motor if it is stopped.
✓
NOTE!
This parameter is applied to all the inverter command sources, but it was created aiming at allowing
the command via HMI to be able to disable the motor by inertia instead of deceleration ramp. In this
way, when P229 = 1, Bit 0 of the control word (Ramp Enable) has a function similar to Bit 1 (General
Enable). The same way, the digital input functions such as: Run/Stop, Forward/Reverse Run stop
the motor by inertia in this condition of P229.

7.2 SPEED REFERENCE

The frequency reference is the value applied to the input of the acceleration ramp module (P001) to control the
frequency applied to the inverter output (P002) and consequently the motor shaft speed.
Inside the CPU, the inverter uses signed 16 bit variables to treat the frequency references. Besides, the full scale of
the reference, output frequency and related variables are defined in 400.0 Hz. On the other hand, depending on the
source, this scale is conveniently modified considering the interface with the user by standardization or application
requirements.
