Setting Motor Inductance Levels
Depending on the construction of your motor, you may need to configure one or more axes to the low
inductance setting rather than the default standard inductance setting. Table 6 shows the motor
inductance level ranges for the two different settings.
Use the last DIP switch on each of the 9-position DIP switch banks to set the motor inductance level for
each axis. Refer to Figures 1 and 3 for the location of the of the motor inductance level switch. Table 7
shows the DIP switch settings for low and standard motor inductance.
