3-1
The ZVD program codes are arranged in groups. A program code is designated by
its group number, followed by a dash, and then its individual number within that
group. For example, the code 05 – 03 indicates it is the third code in the fifth group.
For a full discussion on groups and codes, consult the full code listing.
3. ZVD Program Requirements
3.1 General
3.2.1 To access the program codes, press the PROG/DATA key. The display shows
a number on the left. This is the group number. To go to another group, use
the UP and DOWN arrows.
3.2.2 When the desired group is in the display, press the PROG/DATA key again. A
code number shows up on the right side of the display. Scroll to the correct
code using the UP and DOWN arrows.
3.2.3 When the desired group and code are in the display, press the PROG/DATA
key a third time. The display now shows the value in that code. To change the
value, use the UP and DOWN arrows. If the number in the display is larger
than one digit, the other digits may be accessed using the LEFT arrow.
3.2.4 Once the desired value has been entered in the code, press the PROG/DATA
key a fourth time. The display will show “End”, which means that the change
has been accepted. If it shows “Err”, the code cannot be changed at this
time. The reason may be that the drive is in a “RUN” condition and the code
cannot be changed until it is stopped. Some codes are “READ ONLY”, which
means that they cannot be changed under any conditions, such as codes 00
- 00 and 00 – 01.
3.2 Accessing Program Codes
NOTE: The default program in the ZVD is sufficient for normal pump operation except
for a few codes, listed below. Changing the codes below should meet the needs of
most users. If other functions are desired from the ZVD, consult the full code listing.
Code 00 – 03 (Startup Display Selection) = 2 (User Defined Units, U)
Code 00 – 04 (Multi-function Display) = 11 (encoder RPM)
Code 00 – 05 (User Defined Coefficient) = ____________ (Maximum User Defined
Units/Code 01 – 00 (60.OO Hz))
NOTE: See Appendix B for examples
Code 00 – 09 (Operating Mode) = 3 (Vector with Feedback)
Choices: Volts/Hertz without Feedback (0), Volts/Hertz with Feedback (1),
Vector without Feedback (2), or Vector with Feedback (3)
Code 01 – 09 (Acceleration Rate in Seconds) = ____________ (Default is 10.0)
Code 01 – 10 (Deceleration Rate in Seconds) = ____________ (Default is 10.0)
Code 02 – 00 (Source of Frequency Command) = ____________ (Default is 0 (Keypad))
Choices: Keypad (0), Analog 0 – 10VDC (1), Analog 4 – 20 mA (2), or
RS-485 (4)
Code 02 – 01 (Source of Operation Command) = ____________ (Default is 0 (Keypad))
Choices: Keypad (0), External with keypad stop (1), or RS-485 with
keypad stop (3)
