Operating Guide
3 Product Overview
3.1 Intended Use
OUTPUT FREQUENCY LIMIT
Due to export control regulations, the output frequency of the drive is limited to 590 Hz. For demands exceeding 590 Hz, contact
Danfoss.
The enclosed drive is an electronic motor controller that converts AC mains input into a variable AC waveform output. The frequen-
cy and voltage of the output are regulated to control the motor speed or torque. Depending on the configuration, the drive can be
used in standalone applications or form part of a larger system or installation. The enclosed drive is designed to:
•
Regulate motor speed in response to system feedback or remote commands from external controllers.
•
Provide motor overload protection.
•
Monitor system and motor status.
•
Reduce harmonics and increase the power factor using the optional passive harmonic filter or line reactor.
•
Reduce motor acoustic noise and protect motor insulation with the optional output filters.
•
Reduce bearing current and shaft voltage with the optional common-mode filter.
•
Reduce high-frequency, electromagnetic noise in the motor cables with the optional dU/dt filter.
•
Provide sinusoidal output with optional sine-wave filter.
The enclosed drive is designed for residential, industrial, and commercial environments in accordance with local laws and standards.
Do not use this drive in applications that are non-compliant with specified operating conditions and environments.

3.2 What is an Enclosed Drive?
The enclosed drive is an IP21/54 (NEMA 1/12) enclosure surrounding an IP20 (Protected Chassis) drive to form the basis of the sys-
tem. There are 4 enclosed drive models with varying power ratings.
•
D9h model: 110–160 kW (125–250 hp)
•
D10h model: 200–400 kW (250–450 hp)
•
E5h model: 355–630 kW (450–650 hp)
•
E6h model: 500–800 kW (650–950 hp)
The enclosed drive is available with various power options and input and output filters to create a factory-built, custom drive. Some
options and filters result in extra cabinets attached to the left or right side of the drive cabinet. These optional cabinets are shown
with dotted lines, while the drive cabinet is shaded.
