4.3 Explanation of additional parameters
The following information provides the explanation of additional parameters which are necessary to be used
for SJ-DN2.
4.3.1 P044 (DeviceNet communication watchdog timer)
Set the allowable time that is an interval of polled I/O from DeviceNet master when the inverter is running.
When the timeout occurs, the inverter’s behavior is as set in command P045.
4.3.2 P045 (Inverter action on communication error)
This command decides what action occurs when a communication fault is detected on the network or P044
timeout occurs at the inverter while controlled from DeviceNet.
When set to 0.00, this function is disable.
4.3.3 P046 (Polled I/O OUTPUT Instance number)
This command is instance number of assembly object Polled I/O output. Set the parameter to comply with
table below. (Combination table for P046, P047).
4.3.4 P047 (Polled I/O INPUT Instance number)
This command is instance number of assembly object Polled I/O input. Set the parameter to comply with
table below. (Combination table for P046, P047).
4.3.5 P048 (Inverter action on Idle mode)
This command decides what action occurs when on Idle mode is detected on the network. Inverter can start
to operate after behavior below.
At the time of set to 00, 01:After Idle mode released and fault reset, inputs stop command and run
command.
At the time of set to 02 : After Idle mode released.
At the time of set to 03, 04: After Idle mode released, inputs stop command and run command.
4.3.6 P049 (Motor poles setting for revolutions per minute)
Set the Motor poles for AC Drive device profile.
0 to 38 (even number value only)
Set to 0 when frequency setting (Hz).
Set to 2 to 38 when revolution speed setting (min
-1
).
