Relay Type – Upper Limit Travel with Hysteresis
Selecting relay type
ULim will cause the relay to energize when the motor position exceeds the upper limit
trip point, and can be set up as follows. Note that relay hysteresis parameter (RLY1HY) value is set to 10,
which is 10% of range. This means that when the relay is energized, due to the motor position exceeding
the upper limit value, the relay will not de-energize until the motor moves to 10% below the trip point.

Relay Type – Motor Starts
Selecting relay type STRT will cause the relay to trip when the number of motor starts exceeds the selected
limit. The motor starts value is stored as one of the maintenance group statistics. This example sets the
motor starts limit at 200,000 for Relay 1.

The resulting action is that Relay 1 will trip when the number of accumulated motor starts in the
maintenance group exceeds 200,000.
