LA Series Linear Servo Amplifier Technical Reference Manual

M – Mode

This command is used to view or set the commutation mode of the drive. M0 sets trapezoidal

commutation, M1 sets Sinusoidal 2 phase input commutation. The “M command can only be used to view

the commutation setting if jumpers are installed.

R – Reset

This command causes the drive to perform a power on reset

S – Save Parameters

This command saves the user selectable parameters to NVM.

Y – Display Fault History

The last 8 errors from the fault history buffer are displayed. If a fault occurs while the drive is enabled, the

fault is saved into the fault history buffer. The last 8 errors are saved in NVM and recalled for display when

this command is issued. Only errors that occur while the drive is enabled are stored. This prevents

nuisance errors that commonly occur during startup/shutdown to be ignored.

YC – Clear Fault History

This command clears the fault history buffer in NVM. This command is useful after setting up a new

system in production to be sure any setup errors are cleared.

YS – Display SOA Fault History

This command displays the last saved SOA trip information from NVM. In the event of an SOA trip, all the

system parameters related to the trip are stored. This information is useful to the factory for

troubleshooting SOA events.
