SMC100

Newport SMC100 Single-Axis Motor controller. Used with the HTS magnet system, along with the Smartmonitor and two Kepco PSUs in master/slave configuration.

It has a peculiar startup and homing behaviour - after powering up it must be homed and once homed it cannot be homed again. Unless…

… If the motor refuses to move despite not returning an error code, and an orange/red LED is shown on the front panel, then it simply needs to be re-homed. This is explained on the diagram and table on the cover of the controller.

If running asyn trace, when it is working you may have nothing printed, so I guess It doesn’t look to regularly poll. but all a bit confusion. If you want to run asyn trace, note that the port is called serial1 rather than L0

Connection

DLS system: connected to laptop via a gender changer. It does not seem to need a null modem.

If using correct-gender cable (female cable), then the device does need a null modem.
