Detailed Description of the Parameters
.
CTW900 | 79
For option 4 (DIx), the mode to be selected will depend on the status of the digital input, as follows:
■
DIx open (0V): Local mode;
■
DIx closed (24V): Remote mode.
P0221 – Selection of the Speed Reference Source (Local Situation)
P0222 – Selection of the Speed Reference Source (Remote Situation)
Adjustable Range:
0 = HMI
Factory Setting:
P0221 = 0
1 = AI1
P0222 = 1
2 = AI2
3 = AI3
4 = AI4
5 = AI1 + AI2 > 0 (Sum AIs > 0)
6 = AI1 + AI2 (Sum AIs)
7 = Electronic Potentiometer (E.P.)
8 = Multispeed
9 = Serial/USB
10 = Anybus-CC
11 = SoftPLC
Properties:
CFG1
Groups of
01 PARAMETER GROUPS or 01 PARAMETER GROUPS
Access via HMI:
27 Local Control
........
28 Remote Control
........
Description:
They define the origin source for the Speed Reference in the Local situation and Remote situation.
Some comments on the options of these parameters:
■
When an analog input (AIx) is selected as reference source, the value to be used by the control will be the
result of the analog signal applied to the input added to its offset and multiplied by the input gain (see details
in Figure 7.11);
■
The reference value set by the keys
“
”
and “
”
is defined by parameter P0121;
■
When option 7 (E.P. – Electronic Potentiometer) is selected, it is also necessary to set one of the digital
inputs with option 11 (Accelerates E.P.) and the other with option 12 (Decelerates E.P.). For further details,
refer to section 7.3.14;
■
When option 8 (Multispeed) is selected, it will be necessary to set P0266 and/or P0267 and/or P0268 for
option 13 (Multispeed). For information on this function, refer to section 7.3.11.
P0223 – FWD/REV Selection (Local Situation)
P0226 – FWD/REV Selection (Remote Situation)
Adjustable Range:
0 = Forward
Factory Setting:
P0223 = 2
1 = Reverse
P0226 = 4
2 = FWD/REV Key (Forward)
3 = FWD/REV Key (Reverse)
4 = DIx
5 = Serial/ USB (Forward)
6 = Serial/ USB (Reverse)
7 = Anybus-CC (Forward)
8 = Anybus-CC (Reverse)
9 = Polarity AI4
10 = SoftPLC (Forward)
11 = SoftPLC (Reverse)
12 = Polarity AI2
Properties:
CFG1
Groups of
01 PARAMETER GROUPS or 01 PARAMETER GROUPS
Access via HMI:
27 Local Control
........
28 Remote Control
........
Description:
They define the origin source of the ‘Direction of Rotation’ command in the Local or Remote situation so that the
direction indicated at the end of each option specifies the default selection adopted at the power-up of the
CTW900.
