VLT® Series 2000 Programming Group 5 -- Serial Data Interface Protocol: Using the serial RS 232 port (terminals 71 and 72) you can read and set parameters of the VLT adjustable frequency drive and issue reference and control commands. The serial port can be used for point to point communication between the VLT and a PC. Communication takes place by means of a protocol specified by Danfoss, and using the echo function (parameter 500) you can connect several VLT adjustable frequency drives.
VLT® Series 2000 Byte 1: Start byte, which in this case must be the character "<" (ASCII: 60). Byte 2 and 3: The two-digit address of the adjustable frequency drive. This address is also programmed in parameter 500. Sending to address 00 means transmission to all units connected to the bus. None of the units will reply, but they will carry out the command. Byte 4: Control parameter telling the drive what to do with the following data values.
VLT® Series 2000 Programming VLT Status The four control and status bytes are used to send control commands to the adjustable frequency drive when the telegram is sent from the master and to send status from the VLT to the master when the telegram is returned from the VLT adjustable frequency drive.
VLT® Series 2000 Programming VLT Control Commands OFF 1: Makes a normal ramp stop of the motor and opens the relay output of the VLT (relay off). OFF 2: Makes a motor coast and opens the relay output (relay off) OFF 3: Same as OFF 1, but the motor makes a quick-stop. Bit 10: This bit has to be 1, if any of the control commands should cause a reaction.

When the adjustable frequency drive's output frequency is reduced more quickly than the motor speed (due to inertia) can be changed, the motor will act as a generator. It will send energy back to the VLT and as a result the intermediate circuit voltage will increase.

Appendix; PI Regulation The following instructions will enable quick and easy setup of the PI regulation and associated parameter settings. Detailed information about each parameter can be found in the parameter section of this manual. Parameter 100: Set the load type. There are several choices in each group but variable torque medium or variable torque medium with AEO will suit most pumps or fans. Parameter 101: Select closed loop operation.
Appendix; PI Regulation Example: The set-point is 40%, and the min. speed is 50%. 1. Selecting a new set-point. Choose a value that will raise the set-point about 10% higher than the min. speed. New set-point = % min. speed x 1.1 = 55% 2. Setting parameter 125. Apply the same increase to this parameter. 100 x 1.1 = 110% Parameter 201: Set min. frequency if required. If you enter a min. speed you must observe the following: • When min. speed is used parameter 411 must be set to "proportional with min.
Appendix; PI Regulation External Setpoint For inverse control; modification of the setpoint and feedback signal is required. 12 Link Example: A transmitter has a 0-15 foot span equal to 0-20mA. The PID set-point must be set at 12 feet for inverse control. • Enter 20-0 mA in parameter 413. The normal signal in figure A is converted to an inverse signal as shown in figure B. Start/Stop Parameter 402 (start) 27 16 18 + 50 53 % mA 55 – 100 20 55 0 Figure A. 7.
Appendix; PI Regulation External Manual Control Over-ride It is often necessary to run the machine manually for maintenance reasons. Manual control can be carried out manually from the keypad of all the units. If remote control of the manual over-ride is required additional circuitry is necessary. For the VLT Series 3500 special parameters are available for external manual over-ride. Refer to the VLT Series 3500 instruction manual.
