SD500 StartStop Speed Pot Analogue
This setup is for using start/stop commands by the input terminals and speed reference for the drive by analogue input.
The SD500 series of the VSDs have a very simplistic keypad and screen to use. To familiarize yourself with all the functions the SD500 can offer, please refer to the programming and software manual.
Firstly, wire and connect into the I/O terminals the required start/stop input and the speed reference analogue input.
Be sure to add a link from 5G to CM. Drives up to 22 kilowatts require this.
The analogue shown here is a 0 - 10 volt potentiometer also known as a speed pot. Once you have confirmed your wiring into the I/O terminals is correct, you must ensure that motors are isolated from accidental starting before power up of the drive.
On power up as a good rule of thumb it's a good idea to reinitialize the drive. This ensures that the drive is back to its original default settings: Group 1 G1.5
Setting of the motor name plate is the first parameter to be added. This ensures that the motor is protected correctly and the RPM is correct into the drive: Group 2 G2.2
To enter a group, press the start key.
To scroll press the minus or plus key.
To enter new parameters, press and hold star key - pressing the start or minus key to enter your new parameter.
To move around groups, press the minus or plus key accordingly.
Move now to group 3 references.
In this group, you select where your speed reference is to come from, so for this setup we change ref speed 1 from default local to AI1 analogue input 1, which is the 0 - 10 volt setup.
Move now to group 4.1 in 4.1.1 - we now need to select the control mode.
For all setup, default is number one remote which is correct. The drive is operated through the input terminals.
Now scroll down to 4.1.3. Default here is also star/plus which is correct for our setup.
G4.2 Analogue Input 1
In this group scaling of the analogue can be performed if required.
G 4.2.3 default is zero volts.
G 4.2.4 default is 0%.
G4.2.5 default is 10 volts.
G4.2.6 default is 100%.
G4.2.12 is the maximum frequency for analogue input 1. Default is 50hertz - ensure this is your correct maximum value.
To ensure your analogue is working correctly, you can show this in the visualization screens.
Press and hold the ESC key to jump up to the visualization lines.
Press the star and scroll through using the plus or minus keys to the required groups.
You can now see in the visualization screen your speed pot values moving up and down - your analogue is working correctly.
There are other visual statuses you can bring up too for example, input statuses; DI1 to DI8.
If acceleration and deceleration rate need to changed enter group 5.
Acceleration rate here is 20 seconds default, time required to reach required hertz or percentage on start-up.
Deceleration rate. Default here is 30 time from off command to 0 volt or percentage.
Group 10: Limits
In this group, if you require your motor to run above 50hertz, the limits will need to be changed here from the default settings.
To see if you are happy with all your wiring to your I/O terminals and motor connections, refit the cover to the SD500 and your motor connections.
You may now start your drive by energizing digital input 1, star plus.
