to
: Menu 0 set-up
Adjustment range :
0.00
to
21.51
Factory setting
: See table below.
These parameters are used, in order, to define parameters
46
to
65
in menu 0. These parameters are independent of
the preset configuration.
: Parameter scaling
Adjustment range : 0 to 9.999
Factory setting
: 1.00
This is a multiplication coefficient applied to the motor speed
for expressing the speed in a unit defined by the user (see
5.34
).
Example: To obtain a reading in m/min for an application
where the product is moving 200 mm for each motor
revolution ==>
11.21
= 0.2.
: Unit displayed at power-up
Adjustment range : 0 to 5
Factory setting
: 0
0 (Speed) (Spd): On power-up, the speed is displayed.
The unit depends on the setting of
5.34
(frequency in Hz,
speed in rpm or a unit defined by the user).
1 (Load) (Load): On power-up, the load is displayed.
The unit displayed depends on the setting of
4.21
(motor
load as a % or output current in A).
2 (Speed/Load) (SP.Ld): Displays the speed and the load
alternately, or the current. The display time of each value can
be configured in
11.47
.
3 (USER) (USER): On power-up, the user parameter
selected by
11.49
is displayed.
4 (Speed/User) (SP.US): On power-up, the speed and the
user parameter selected by
11.49
are displayed alternately.
5 (Load/User) (Ld.US): On power-up, the load and the user
parameter selected by
11.49
are displayed alternately.
: Serial address
Adjustment range : 0 to 247
Factory setting
: 1
Used to define the drive address in the case of control or
supervision via the serial link in Modbus RTU. Avoid values
containing a zero as they are used to address groups of
drives.
: Serial mode
Adjustment range : 0 or 1
Protocol used for communication via the serial link.
0 (LS NET) (LSnt): LS Net protocol.
1 (Modbus RTU) (rtu): Modbus RTU protocol.
: Baud rate
Adjustment range : 0 to 9
Factory setting
: 6
Used to select the data transfer speed in Modbus RTU.
Note: If the CT Comms cable is used, the baud rate is limited
to 38400 baud.
: Min comms transmit delay
Adjustment range : 0 to 250 ms
Factory setting
: 2 ms
As the serial link is 2-wire type, Rx is connected to Tx and Rx\
to Tx\. A communication fault may occur if the receiver
responds to a request before the sender has had time to
switch. Parameter
11.26
is used to introduce a time between
reception and the data feedback. After transmitting a request,
the drive requires 1.5 ms before receiving the next command.
The adjustment is made in 2 ms intervals.
: Modbus RTU frame format
Adjustment range : 0 to 3
Factory setting
: 0
0 (NONE,2STOP) (OP.2S): No parity, 2 stop bits
1 (NONE,1STOP) (OP.1S): No parity, 1 stop bit
2 (EVEN,STOP) (eP.1S): Even parity, 1 stop bit
3 (ODD,1STOP) (oP.1S): Odd parity, 1 stop bit
: Not used
: Drive software version
Adjustment range : 1.00 to 9.99
Indicates the drive software version.
