Reviewed Product View
The supplied Monarch-branded front view has been cleaned and placed on the standard white-background layout without changing the housing, keypad, warning label or brand marking. A separate Inovance-branded angle was not mixed into the gallery because the physical branding differs.

Frequently Asked Questions
Are ME320LN and MD380L interchangeable?
No. ME320LN is a closed-loop elevator drive, while MD380L is an open-loop series. Match the complete model and control architecture.
Do 7.5, 11 and 15 kW use the same frame?
The reviewed official brochure lists the same 208 × 322 × 192 mm frame for these three models, but mounting and clearance must still be checked on the supplied unit.
What must be prepared before commissioning?
Prepare the exact manual, motor and encoder data, brake and rescue arrangements, I/O and communication records, option-card list and parameter backup.
Selection note: Final wiring, parameter loading and elevator safety validation must be performed by qualified personnel using the exact supplied-unit nameplate and manual.
