Motor data may either be selected form the built in motor database or entered by the engineer as a custom motor.
The Motor page has two options at the top of the page that need to be selected.

“Database” is selected by default and the screen will show the motor database selector.

Figure 9-10 Motor type selection

“Induction Motor” is selected by default. This selection will filter the motor database to the selected type. It also displays only the appropriate
“User” settings if a custom motor is required.

Motor database

At the left hand side is a list of manufacturers whose motors are in the database. Select the appropriate manufacturer from the list. If your motor’s
manufacturer is not shown in the list then you will need to provide custom “User” data instead.

Once the manufacturer is selected, the list of motor models will be displayed. The model list is sorted by the manufacturers part number. Select
your motor from the list. The motors data and image will then be displayed so you can ensure you have the correct one selected.

Custom Motor

Custom motor data is entered in this page. The page is split into two parts. On the top are “Basic” motor parameters and below are more
advanced ones. Nominal defaults will have been set, depending on the size of inverter being configured. The Engineer should adjust these
default values with data from the motor nameplate or technical specification.

COMMISSION THE DRIVE

Figure 9-14 Programming the Drive

The “Commission” page is used to commission the Drive with the Selected macro and motor settings chosen during the Wizard.

There are two steps that are performed to finalise the Commissioning of the Drive.

1. Enter the Project File name and the Drive’s name in the left of the screen.

2. “Program Drive”. This step writes your settings to the Drive and overwrites any existing configuration in the Drive.

After these steps, the Drive is ready to use.

Trips & Fault Finding

Trips and Fault Finding

WHAT HAPPENS WHEN A TRIP OCCURS

When a trip occurs, the drive’s power stage is immediately disabled causing the motor and load to coast to a stop. The trip is latched until action
is taken to reset it. This ensures that trips due to transient conditions are captured and the drive is disabled, even when the original cause of the
trip is no longer present.

Keypad Indications

If a trip condition is detected the activated alarm is displayed on the GKP display.

RESETTING A TRIP CONDITION

All trips must be reset before the drive can be re-enabled. A trip can only be reset once the trip condition is no longer active, i.e. a trip due to a
heatsink over-temperature will not reset until the temperature is below the trip level.
You can reset the trip as follows:

1. Press the

(STOP) key to reset the trip and clear the alarm from the display.

2. In remote terminal sequencing mode, create a 0 to 1 transition on the RESET TRIP bit, (bit 7), in the App Control Word parameter.

3. In remote communications sequencing mode, create a 0 to 1 transition on the RESET TRIP bit, (bit 7), in the Comms Control Word

parameter.

Trip Messages

If the drive trips, then the display immediately shows a message indicating the reason for the trip. The possible trip messages are given in the
table below.

Trip Name

Possible Reason for Trip

Criteria for Warning

OVER VOLTAGE

The drive internal dc link voltage is too high:

•

The supply voltage is too high

•

Trying to decelerate a large inertia load too quickly; DECEL TIME time too short
The brake resistor is open circuit
To help prevent this trip, enable the DC Link Volts Limit feature

Internal dc link voltage has
reached midway between the
over voltage trip level and the
dynamic braking resistor control
voltage.

UNDER VOLTAGE

DC link low trip:

•

Supply is too low/power down

Internal dc link voltage has
reached midway between the
lowest expected instantaneous
voltage and the under voltage
trip level.

more consecutive overcurrent
events are encountered (whereas
five consecutive events are
required for a Trip to occur).
