7.5 Procedure for Transferring User Constants

The procedure for changing (transferring) user constants (parameters) after power is turned ON is
to transfer the Servomotor selection, encoder selection (encoder type and number of pulses), elec-
tronic gear ratio, and other user constants in order only. Randomly transferring user constants can
cause a user constant setting warning and they may not be received.
Motor selection, encoder selection, and electronic gear ratio parameters can be changed only once
after power is turned ON. This must be done prior to executing the SENS_ON command and the
motor running.
