330 Unidrive SP Advanced User Guide
www.controltechniques.com Issue Number: 10
Defines the baud-rate (or bits-per-second) for the on-board EIA-RS485 port. The following are supported:
Note that this parameter is not relevant when the EIA-RS485 port mode is set to 25 (CTSync Master) or 26 (CTSync Slave).
Defines a fixed delay between receiving a message on the EIA-RS485 port and the response being transmitted. This can be useful in 2-wire
configurations where it takes a finite time for the master (host) to switch from transmit mode to receive mode. There is always at least a 1ms delay
and this parameter can be used to extend it.
This parameter allows a 1ms delay to be introduced between the Applications module enabling the EIA-RS485 transmitter and actually commencing
the transmission. This should only be required if it is found that the recipient of the transmission is receiving a corrupted start of message.
This parameter is available on SM-Applications Lite module but is not allowed to be set to a 1 (On). Controls where the output of the DPL PRINT
command is sent. If set to zero (Off), the output is sent to the programming client (SyPTPro) and if set to 1 (On) it will be sent to the EIA-RS485 port.
Defines the scheduling period (tick-time), in milliseconds, for the DPL CLOCK task. A value of zero will disable the CLOCK task.
Prior to version 01.05.00 Unidrive SP the default for this parameter was 0ms (disabled).
Defines the scheduling rate for the POS tasks to suit the application performance and the resource needed to run the user DPL program. The
following values are defined::
Set this parameter in order for the user DPL program to automatically run at power-on/reset. If this is changed and the new setting needs to be used
on power-up ensure that a drive parameter save is performed.
