6.2.3 MC1000 INPUTS AND OUTPUTS
The drive has two analog inputs (0-10 VDC and 4-20 mA) that can be used for speed
reference, PID set point reference, or PID feedback. A speed potentiometer (10,000
Ohm) can be used with the 0-10 VDC input.
There are also two analog outputs: one is proportional to speed (frequency), and
the other is proportional to load.
The drive has three programmable outputs for status indication: one Form C relay
and two open-collector outputs.
NOTE: Models rated above 30 Hp at 200/240 Vac and 60 Hp at 400/480 Vac have
a second Form C relay.
Refer to Sections 14 - CONTROL WIRING and 15 - CONTROL WIRING DIAGRAMS
for more information.
7 INSTALLATION
WARNING!
Drives must not be installed where subjected to adverse environmental
conditions! Drives must not be installed where subjected to: combustible,
oily, or hazardous vapors or dust; excessive moisture or dirt; strong
vibration; excessive ambient temperatures. Consult Lenze AC Tech for
more information on the suitability of a drive to a particular environment
The drive should be mounted on a smooth vertical surface capable of safely
supporting the unit without vibrating. The LCD display has an optimum field of view,
this should be considered when determining the mounting position.
Chassis models must be installed in an electrical enclosure that will provide complete
mechanical protection and maintain uniform internal temperature within the drive’s
ambient operating temperature rating. All drive models MUST be mounted in a
vertical position for proper heatsink cooling.
Maintain a minimum spacing around the drive as follows:
SPACING REQUIREMENTS

0.25 - 5 2 50
7.5 - 25 4 100
30 - 60 6 150
75 - 150 8 200
All drive models MUST be mounted in a vertical position for proper heatsink cooling.
Fans or blowers should be used to insure proper cooling in tight quarters. Do not
mount drives above other drives or heat producing equipment that would
impede the cooling of the drive. Note the ambient operating temperature ratings
for each drive model.
