6.2.6 Relationship of SERVOPACK Parameters to SVB-01 Parameters
6-66
„ Parameters that Must Be the Same for SVB-01 and SERVOPACK
Motion control will not function properly if the following parameters are not the same.
„ Parameters Set Either on Controller or SERVOPACK
Motion control will not function properly if both the following sets of parameters are used at
the same time.
Do not normally use the gear ratio parameters on the SERVOPACK. Set the following parameters at
setup.
• When using a Σ Series SERVOPACK, set both parameters Cn-0024 and Cn-0025 to 1.
• When using a Σ-II Series SERVOPACK, set both parameters Pn202 and Pn203 to 1.
„ SERVOPACK Parameters That Must Not Be Used
* Use the setting parameter No. 37: External Positioning Travel Distance
(OL††24) for the final travel distance when executing the external
positioning command. The SERVOPACK parameter Pn814 is not used.
• When using a Σ Series SERVOPACK
Always mask P-SOT and N-SOT on SERVOPACK by setting the bits 2 and 3 of Cn-0014 to 1 at setup.
• When using a Σ-II Series SERVOPACK
Set the 1st digit of the parameter Pn801 to 3 (software limit disabled in both directions).
