Getting Started
3. Enter the minimum and maximum speeds (if required to be different from default settings):
•
Parameter P-01: Maximum frequency – Default: 50.0Hz.
•
Parameter P-02: Minimum frequency – Default: 0.0Hz.
50Hz is equivalent to:
2 pole motor: 3000rpm
4 pole motor: 1500rpm
6 pole motor: 1000rpm
8 pole motor: 750rpm
4. Enter the acceleration and deceleration ramps (if required to be different from default settings):
•
Parameter P-03: Acceleration ramp – Default: 5.0s.
•
Parameter P-02: Deceleration ramp – Default: 5.0s.
NOTE:
The acceleration and deceleration ramps should be set according to the load type. Heavy starting
torque and high inertia type loads require longer acceleration and deceleration ramp times.
5. Enter the motor nameplate details:
•
Parameter P-07: Motor rated voltage – Default: 230V / 400V.
o
Usually the default settings are OK for standard motors.
•
Parameter P-08: Motor rated current – Default: Dependent on drive rating.
o
Enter the nameplate current. This provides motor thermal current overload protection (I
2
t).
•
Parameter P-09: Motor rated frequency – Default: 50Hz.
o
Usually the default setting is OK for standard motors.
NOTE: For the majority of applications, especially high inertia loads (fans), P-10 (Motor rated speed) does
not need to be set.
6. Set the primary control mode:
•
Set the primary control mode, Parameter P-12 (Default = 0, terminal control).
o
P-12 = 1: Uni-directional keypad control (Forward only).
o
P-12 = 2: Bi-directional keypad control (Forward and reverse).
7. Run (Enable) the drive:
•
Close the connection between terminal 1 (24VDC) and terminal 2 (Stop/Run).
•
Press the Green RUN button on the drives keypad. The display should show:

•
Press the UP button to increase the speed of the motor.
•
Press the DOWN button to decrease the speed of the motor.
•
Pressing the Red STOP button will cause the motor to ramp to a stop.
•
If P-12 = 2, while running at speed, if the Green RUN button is pressed, the motor will decelerate to
zero speed and then accelerate back up to speed in the reverse direction of motor rotation.
•
While running, if the connection between terminals 1 and 2 is opened, the drive will decelerate to
zero speed and then disable.
8. Drive Reset
•
If the drive trips, it can be reset by pressing the RED Stop/Reset button or by opening and closing the
connection between terminals 1 and 2.
