Terminals 21 and 20
Programmable Contact CR2
These terminals allow drive supplied relay contact CR2 to be used in
external circuits. When power is applied to the drive, the N.O. contact will
remain N.O. until a programmed signal is received. The contact is
programmed by Parameters 23 and 25 to signal that the drive is at the
programmed set speed or 140% of rated drive current. The contact is
isolated from Logic Common and other drive circuitry.

Fault Contacts -- CR3
These terminals allow drive supplied CR3 relay contacts to be used in
external circuits. The contacts are shown with power applied to the drive.
When power is first applied to the drive, the contacts will change state ––
22 to 23 will close, 23 to 24 will open. Should a fault occur 22 to 23 will
open, 23 to 24 will close. The contacts are isolated from Logic Common
and other drive circuitry.
