Operating the Inverter
4-5
605C Frequency Inverter
Local Control using the Operator Station
Note: Refer to Chapter 5: “The Operator Station” to familiarise yourself with the Operator
Station’s LED indications, and how to use the keys and menu structure.
The following start-up routine assumes that the Operator Station is fitted and is in default mode,
and that the Inverter’s control terminals are wired as shown in Figure 3-9 Typical Connections
to the Control Terminals.
1. Power-up the unit. The display will show the power-up screen ,“AC MOTOR DRIVE”.
After a few seconds, SETPOINT (REMOTE) % will appear on the display.
The HEALTH, STOP, and FWD LEDs will light.
If the HEALTH LED flashes, the Inverter has tripped. The display will indicate the reason
for the trip. Refer to Chapter 7: “Trips and Fault Finding” to investigate and remove the
cause of the trip. Reset the trip condition by pressing the
Stop/Reset key on the keypad. The
HEALTH LED will now light.
2. Press the L/R (Local/Remote) key to enable Local control. Both the LOCAL SEQ and
LOCAL REF LEDs will light when Local control in enabled.
3.
Press the RUN key. The RUN LED will light and the motor will rotate slowly. (The RUN
LED would flash if the setpoint was at zero.)
4. Reverse the motor’s direction of rotation by pressing either the DIR key, or by swapping
two of the motor phases (WARNING: Disconnect the mains supply first) .
Setting-up the Inverter
The Inverter is set-up using the Autotune feature, the Operator Station, or a suitable PC
programming tool. It can be run in Sensorless Vector Fluxing mode, or as a simple Open-loop
Inverter (V/F fluxing).
Quick Set-up as an Open-loop Inverter (V/F fluxing)
By loading a different macro, you are installing the default settings for
that macro’s application. Once a macro has been loaded (or the default
is used), the parameters most likely to require attention are contained
in the QUICK SETUP menu at level 2.
Parameters Default Brief Description
BASE FREQUENCY * 50.0 Hz Frequency at which Inverter gives maximum output volts
MAX SPEED * 50.0 Hz Max speed clamp and scale factor for other speed
parameters
MIN SPEED -100.00 % Min speed clamp
RAMP ACCEL RATE 10.0 s Acceleration time from 0Hz to max speed
RAMP DECEL RATE 10.0 s Deceleration time from max speed to 0Hz
V/F SHAPE LINEAR LAW Constant torque V to F characteristic
QUADRATIC TORQUE FALSE Selects higher continuous rating with less overload
capability (Chapter 6: Quadratic Torque Selection)
FULL LOAD CALIB ** 3.4 A Calibrates Inverter to motor full load current
NO LOAD CALIB ** 1.9 A Calibrates Inverter to motor no load current
POWER FACTOR ** 0.80 Set this to the motor power factor rating
MOTOR CURRENT xxxx.x A Motor current diagnostic (read only)
MOTOR I LIMIT 100.00% Level of motor current as % of FULL LOAD CALIB
FIXED BOOST 6.00 % Boosts starting torque by adding volts at low speed
RUN STOP MODE RAMPED Ramp to standstill when RUN signal removed
JOG SETPOINT 10.0 % Inverter speed setpoint whilst jogging
AIN 1 TYPE 0..+10V Input range and type
AIN 2 TYPE 0..+10V Input range and type
DISABLED TRIPS 0600 >> Sub-menu to set disabled trips
DISABLED TRIPS+ 0000 >> Sub-menu to set additional disabled trips
