5.8.1 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.
5.8.2 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 pa-
rameters. Disable the expansion module by setting "I/O type" = "Pulse input" in order
to disable the internal communication between the module and the motor. After 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" but-
ton 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.
