Record nominal power, current, voltage, etc. ratings taken

from your motor nameplate (to use in the ratings

comparison tables)

What type of signal is the speed/frequency command? e.g.

0-10VDC, 4-20 mA, via communications, or other?

Where is the speed/frequency command landed on the

What type of signal is the start/stop command? e.g. a relay

closure, via communications, or other?

Where is the start/stop command terminated on the drive?

Are there any other control or reference sources that

Are you using a door mounted control panel on an

enclosure door? If so, consider appropriate kit/method for

replacement keypad.

Are you using a door mounted control panel? Consider this

when choosing options

Consider the dimensions and mounting requirements,

cable sizes and heat losses

Review the control terminal wiring and ensure the cable

lengths are sufficient

Is the Building Automation System communicating with the

drive over a communication protocol? e.g. BACnet. If so,

document the appropriate communication settings, such

as MAC ID, Device Object Instance ID, Baud, etc.

Are there any analog outputs from the drive that are wired

to another device? If so, document the type of signal (e.g

4-20 mA), where it was terminated on the drive, what it was

used for, and any scaling of the signal.

Are there any relay outputs from the drive that are wired to

another device? If so, document where it was landed on the

drive and what it was used for.

Are there any other control or reference sources that

require additional IO options?
