Speed regulation is defined as follows:
∗2.
Set Pn001 to n.
2 if you will not use the dynamic brake.
(2) Basic Specifications of SERVOPACKs and Converters
Basic specifications of SERVOPACKs and converters are shown below.
∗1.
Set Pn001 to
2 in the multi-winding drive unit parameters if you will not use the dynamic brake.
∗2.
Implement risk assessment and confirm that the safety requirements of the machine have been met.
Regenerative Processing
Included.
External regenerative resistor units are required for the converters.
Overtravel Prevention (OT)
Dynamic brake stop, deceleration to a stop, or coasting to a stop at P-OT or
N-OT
Protective Functions
Overcurrent, overvoltage, insufficient voltage, overload, regeneration error,
and so on.
Utility Functions
Gain adjustment, alarm history, JOG operation, origin search, and so on.
