Logical Command and Speed Reference
MW500 | 7-15

Table 7.6: Control word
Bit Function Description
0 Ramp Enable
0: Stops the motor by deceleration ramp
1: Turn the motor according to the acceleration ramp until reaching the speed reference value
1 General Enable
0: Disable the inverter completely, interrupting the power supply to the motor
1: Enable completely the inverter, allowing the operation of the motor
2 Run Clockwise
0: Run the motor in the opposite direction of the reference signal (counter clockwise)
1: Run the motor in direction of the reference signal (clockwise)
3 JOG Enable
0: Disable JOG function
1: Enable JOG function
4 Remote
0: Inverter goes into Local mode
1: Inverter goes into Remote mode
5 2
nd
Ramp
0: Acceleration and deceleration ramp by P0100 and P0101
1: Acceleration and deceleration ramp by P0102 and P0103
6 Quick Stop
0: Quick Stop inactive
1: Quick Stop active
7 Fault Reset
0: Not Used
1: If in fault state, reset the fault
8 to 15 Reserved

Description:
This parameter defines the motor stop mode when the inverter receives the “Stop” command. Table 7.7 on
page 7-15 describes the options of this parameter.
Table 7.7: Selection of stop mode
P0229 Description
0 The inverter will apply the stop ramp programmed in P0101 and/or P0103
1 The motor will run free until it stops
2 The inverter will apply the stop ramp programmed in P0106
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 P0229 = 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 and Command with Three Wires Turn off the motor by inertia in this condition of P0229.
7.3.1 Control via HMI Inputs
Contrary to the network interfaces and SoftPLC, the HMI commands do not access the inverter control word
directly, because of limitations of key functions and HMI behavior. The HMI behavior is described in chapter 4 HMI
AND BASIC PROGRAMMING on page 4-1.
