1.7.7 Changing the CANopen node address (Node ID)
The CANopen node address of the device can be changed in this
way or also adapted via the fieldbus menu.
Change via the object list using default SDO traffic.
The object list index 3F40h, subindex 1 can be used to read the node address currently configured or to
configure a new node address.
The permitted range for the node address is 1..127. The default node address is 119.
The data type of this entry is UNSIGNED SHORT.
1. To change the node address, the new address is written to
index 3F40h, subindex 1.

2. Writing the “save” signature to index 1010h, subindex 05
causes the new node address to be saved in the non-volatile
memory.

3. The changed baud rate becomes effective when the device is
next started. The device can also be restarted via the NMT
command “ResetNode”.

Transfer rate (baud rate)
When supplied, the device is set to a baud rate of 125 kbit/s.
Possible Baud rates that can be set are:
n 10 kbits/second
n 20 kbits/second
n 50 kbits/second
n 100 kbits/second
n 125 kbits/second
n 250 kbits/second
n 500 kbits/second
n 1000 kbits/second
1.7.9 Calibration, explanations
The pump is pre-calibrated. The metering volume can be recali‐
brated if required.
