Commands & Referencies
S.200 Cmd source sel
(Command source selection)
It defines the use of the main commands START and STOP .
S.200 = 1 START & STOP via terminals
In this configuration the commands are active through the drive terminals.
The motor START command can be performed by applying the specific logic level (high level +15V) ,
to the Digital Input 1 (terminal 5), factory set as RUN If this connection is removed, the motor
will STOP with the set ramp time.
For this connection refer to figure 5.3.2.1.
N

!
After a cycle of main supply voltage, the drive can be started only according to the settings of
P.003 Safety
parameter, which allows the Start/Stop commands to respond to
Edge
or
Level
sensitive
signals (see chapter 7.6 for more details).

!
Other configurations for the setting of the "main commands" are described in the chapter
PARAMETERS
, section
Commands
.
Main Commands Logic Control:
START & STOP
The START & STOP function configuration is correlated to other functions and parameters as well as the
mode to REVERSE the motor speed.
These functions allow additional control logic and safety control.

.
MOTOR SPEED REVERSAL
There are several way to REVERSE the speed direction of the motor.
As a default factory setting, the Digital Input 2 (terminal 7) is programmed to this purpose.
All of the frequency references or other variables controlled with digital setting or analog signal, can be
programmed either with positive or negative values. The polarity of the value (Digital or Analog) will determine the
motor rotation direction, without the use of any external HW commands.
Despite the polarity of the reference, the REVERSE command, if programmed on a digital input, will always
reverse the speed direction of the motor.
S.201 Max ref freq
(Maximun reference frequency)
It is the threshold for the analog or digital reference and the maximum speed for both directions.
This parameter applies to the sum of the two references value available on the drive.
