A.2 Drive Specifications
Table A.3 Drive Specifications
Item Specifications
Efficiency
<1> Adjustments, e.g. to parameters, are required after auto-tuning.
<2> When the momentary power loss compensation function is used, an uninterruptible power supply unit for the control power supply is needed
(this is an option).
<3> To use the communications function, additional wiring and the installation of an option card must be done.
For Ethernet or CP-215 communication, an optional expansion PLC board is required.
<4> UL and cUL standards: A waiting approval.
