AP1. BASIC CONFIGURATION – Drive control using the keypad – VSD1-D, VSD3-D
The AC Variable Speed drives (VSD*/A) supplied by SODECA are meant to be handled using the keypad.
This section explains how to configure the “BASIC CONFIGURATION” control mode. This basic control mode allows
to start and stop the drive using its keypad, START y STOP keys, and change the rotation speed of the motor
with the y keys, without using the exterior control KIT.
1.1 PROGRAMMING
Use the next table to change to the basic configuration mode.
Table “BASIC CONFIRGURATION”
1.2 WIRING
Before the start of the programming, wire the L1-L2-L3 input phases when using three phase equipment and wire the
L1-L2/N input phases when using single phase equipment.
Once the “BASIC CONFIGURATION” control mode is selected, that is after introducing the parameters of the basic
configuration table (section 1.1), use a copper wire to short-circuit the terminals 1 and 2 of the VSD*/A. This short-circuit
enables the keypad control mode (See Fig. 1). This short-circuit can be changed with an external signal which would
prevent enabling the drive when the bridge between terminal 1 & 2 is open.
1.3 “BASIC CONFIGURATION” OPERATION MODE
1. Ensure the bridge between terminals 1 & 2 is closed. The display will show
2. Press the START key. The display will show and the drive will increase the speed until it reaches the
minimum speed programmed in the parameter.
3. Press to increase speed.
4. The drive will increase gradually, with the acceleration ramp previously programmed, until the key is no longer
pressed. The acceleration ramp is adjusted in theparameter, check before the start.
5. Press to decrease speed. The drive will decrease speed until the key is no longer pressed.
The acceleration ramp is adjusted in the parameter.
6. Press the STOP key. The drive will decrease its speed and stop. The acceleration ramp is adjusted in the
parameter.
7. The display will show . The drive is disabled.
8. In order to program the speed without pressing start, that is when the display is showing , press the STOP
key while the drive is disabled and the display will show the objective speed. Use the y keys to adjust the
wanted speed value. Press the STOP key to show on the display again.
9. Press START, the drive will accelerate towards the objective speed.
10. While the drive is enabled, we can visualize the consumption of the motor by pressing the navigator key >2
seconds.
