6.5 Terminal Control
When delivered, the VS1STS is set to operate in terminal control mode and all parameters (P-xx) have the default values as
indicated in Chapter 7 Parameters. Connect the motor to the drive, checking star/delta connection for the voltage rating.
1. Remove all power from the control.
2. Connect a control switch between the control terminals 1 and 2 ensuring that the contact is open (drive disabled).
3. Connect a potentiometer (1kΩ min to 10 kΩ max) between terminals 5 and 7, and the wiper to terminal 6.
4. With the potentiometer set to zero, switch on the power supply to the drive.
The display will show
.
5. Enter motor data from motor nameplate:
P1-01 = motor rated voltage
P1-02 = motor rated current
P1-03 = motor rated frequency
P1-04 = motor rated speed
6. Close the control switch between terminals 1-2. The drive is now ‘enabled’ and the output frequency/speed are
controlled by the potentiometer.
7. On first enable from factory default parameters, the VS1STS will carry out an Auto tune (as described in Section 6.7), and
the display shows
. Leave the control switch closed and allow this to complete.
8. Following completion of the Auto tune, the display shows zero speed in Hertz (
.
) with the potentiometer turned to
minimum.
9. Turn the potentiometer to maximum. The motor will accelerate to 60Hz (the default value of P1-06) under the control of
the accelerating ramp time P1-10. The display shows 60Hz (
6.
) at max speed.
10. To display motor current (A), briefly press the ENT/PROG key.
11. Press ENT/PROG again to return to speed display.
12. To stop the motor, either turn the potentiometer back to zero or disable the drive by opening the control switch (terminals
1-2).
13. If the enable/disable switch is opened the drive will decelerate to stop at which time the display will show
. If the
potentiometer is turned to zero with the enable / disable closed the display will show
.
. (0.0Hz), if left like this for 20
seconds the drive will go into standby mode, display shows
, waiting for a speed reference signal.
6.6 Keypad Control
To allow the VS1STS to be controlled from the keypad in a forward direction only, set P1-07 =1:
1. Connect Motor as for terminal control above.
2. Enable the drive by closing the switch between control terminals 1 & 2. The display will show
.
3. Press the START key. If this is the first enable from factory default parameters, the drive will carry out an Auto tune as
described in section 6.7. On completion of the Auto tune, the display shows
.
.
4. Press the UP arrow to increase speed.
5. The drive will run forward, increasing speed until the UP arrow is released. The rate of acceleration is controlled by the
setting of P1-10, check this before starting.
6. Press the DOWN arrow to decrease speed. The drive will decrease speed until DOWN is released. The rate of
deceleration is limited by the setting in P1-11.
7. Press the STOP key. The drive will decelerate to rest at the rate set in P1-11.
8. The display will finally show
at which point the drive is disabled.
9. To preset a target speed prior to enable, press the DOWN arrow key while the drive is stopped. The display will show
the target speed, use the UP & DOWN arrow keys to adjust as required then press the STOP key to return the display to
.
10. Pressing the START key will start the drive accelerating to the target speed.
Setting P1-07=2 allows the VS1STS to be controlled in a forward and reverse direction from the keypad.
11. Operation is the same as when P1-07=1 for start, stop and changing speed.
12. Press the START key. The display changes to
.
.
13. Press the UP arrow to increase speed the drive will run forward, increasing speed until the UP arrow is released.
Acceleration is limited by the setting in P1-10. The maximum speed is the speed set in P1-06.
14. To reverse the direction of rotation of the motor, press the START key again.
