6.8.1 Troubles related to communication with the motor
Problem: "RS232 - MacTalk is not communicating with the motor"
The status at the bottom of the screen shows "*** No Connection ***" but the power
LED on the motor is lit and the serial cable is connected.
Action:
- Check that the right COM port is selected in the MacTalk "Setup" menu. If a USB to
RS232 converter is used, the COM port normally must be selected as COM3 or
COM4.
- Check that the connection to the motor is made according to the specifications. If
using only one motor on the RS232 line, the TX-PD must be shorted to TX, other-
wise communication can be very unstable. See also the individual descriptions by
each module in chapter 4.
- Ensure that a firmware update has not been interrupted before the communication
problem was observed. If such an update is aborted/interrupted, it must be restarted
and completed before the internal processor is back to normal and can handle com-
munication.
6.8.2 Troubles related to the setup of the motor
Problem: "The motor is not behaving as expected"
Action 1:
Check that the following registers are set properly:
"Torque": 300%
"Velocity": >0
"Acceleration": >0
"Load": 1.00
"In position window": If set too low, it can cause the motor to remain stationary.
Please note that if an expansion module is mounted, it can overrule some of these
parameters. Disable the expansion module by setting "I/O type" = "Pulse input" in
order to disable the internal communication between the module and the motor. Af-
ter the fault diagnosis/correction is complete, remember to switch "I/O type" back
to "Serial data".
Action 2:
Load default by using the "Load default" function in the "Motor" menu.
Alternatively clear the complete memory by using the "Update Firmware" option in
the "Updates" menu.
Problem: "The parameter setup is lost after reset"
The parameters must be saved permanently in the motor using the "Save in flash"
button at the top of the main window. When activating this button, the motor will go
into passive mode while the parameters are saved. After 5-10 seconds the motor will
start up again with the new parameters. If the motor still starts up with the default
setup or a setting made at a much earlier stage, the save procedure has failed.
Action:
Ensure that the motor has the newest firmware (>V5.1). The firmware version for
the actual motor can be seen in the status bar.
Ensure also that the MacTalk program is the newest version (>V1.21).
Both Motor and MacTalk can be updated from the internet using the "Update" menu
at the top of the main screen.
