∗2. Available after the SENS_ON command is input.
∗3. When either 0002H or 0003H is selected for the Speed Unit (parameter 41), set the Speed Base Unit (parameter 42)
to a number between -3 and 0.
∗4. When 0004H is selected for the Speed Unit (parameter 41), set the Speed Base Unit (parameter 42) to 0.
Note: When using parameters that are enabled after restarting the SERVOPACK, a CONFIG command must be input or
the power must be turned OFF and then ON again.
