Module Parameters
32
[RTU Tx Delay 2]
Sets the CH2 inter-frame delay used to delay the
sending of a transmit packet when the module is in
Multi-Drive mode and Parameter 22 - [DSI I/O
Cfg 2] is set to “5” (RTU Master). If this value is
set to 0 (zero), the ModBus default delay of 3.5
character times is used.
Default:
0 milliseconds
Minimum:
0 milliseconds
Maximum:
500 milliseconds
Type:
Read/Write
Reset Required:
Yes
33
[RTU MsgTimeout 2]
Sets the amount of time in seconds that the
module will wait for a response from a ModBus
RTU CH2 slave when the module is in Multi-Drive
mode and Parameter 22 - [DSI I/O Cfg 2] is set to
“5” (RTU Master).
Default:
2 seconds
Minimum:
0 seconds
Maximum:
60 seconds
Type:
Read/Write
Reset Required:
Yes
34
[Idle Action 3]
Sets the action that the module and CH3 drive(s)
take if the module detects that the controller is in
program mode or faulted. This setting is effective
only if I/O that controls the drive is transmitted
through the module.
Default:
0 = Fault
Values:
0 = Fault
1 = Stop
2 = Zero Data
3 = Hold Last
4 = Send Flt Cfg
Type:
Read/Write
Reset Required:
No
35
[Flt Cfg Logic 3]
Sets the Logic Command data that is sent to the
CH3 drive(s) if Parameter 34 - [Idle Action 3] is
set to “4” (Send Flt Cfg) and the controller is idle.
The bit definitions will depend on the drive(s) to
which the module is connected. See
Default:
0000 0000 0000 0000
Minimum:
0000 0000 0000 0000
Maximum:
1111 1111 1111 1111
Type:
Read/Write
Reset Required:
No
36
[Flt Cfg Ref 3]
Sets the Reference data that is sent to the CH3
drive(s) if Parameter 34 - [Idle Action 3] is set to
“4” (Send Flt Cfg) and the controller is idle.
Default:
0
Minimum:
0
Maximum:
65535
Type:
Read/Write
Reset Required:
No
37
[DSI I/O Cfg 3]
Sets the number of CH1 drives that are used in
Multi-Drive mode. Identifies the connections that
would be attempted on a reset or power cycle.
Default:
0 = Drive 0
Values:
0 = Drive 0
1 = Drives 0…1
2 = Drives 0…2
3 = Drives 0…3
4 = Drives 0…4
5 = RTU Master
Type:
Read/Write
Reset Required:
Yes

ATTENTION: Risk of injury or equipment damage exists. Parameter 34 - [Idle
Action 3] lets you determine the action of the module and CH3 connected
drive(s) when the controller is idle. By default, this parameter faults the drive. You
can set this parameter so that the drive continues to run. Precautions should be
taken to ensure that the setting of this parameter does not create a risk of injury or
equipment damage. When commissioning the drive, verify that your system
responds correctly to various situations (for example, a disconnected drive).
