Lenze EDS4900U-REG - Manual (Page 103)

Configuration
7-12 48XX/49XXSHB0399
Note!
If the field terminals (I, K) or the polarity of the actual value encoder is reversed
(resolver, tacho), a TRIP message is sent (see chapter 8.1). After checking and
correcting the wiring, the drive can be commissioned again. If the speed becomes
stable and the drive is operating with tacho feedback, the speed required can be
adjusted.
1. Adapt the rated tacho voltage on board 4902MP by using the DIP
switch (see chapter 4.3.4).
2. Set C025 (”encoder selection”) to -2-.
3. Select C029 (”automatic adjustment”).
4. Enable controller (X2/28).
5. Machine accelerates to speed xxx.
6. Measure speed with hand tacho.
7. Enter measured speed under C029 using the keypad.
8. Accept with SH+PRG.
9. The entered value will be accepted and the machine accelerated to the
correct speed with the time T
i
of the ramp function generator.
Adjustment of additional set-value
Z
set
is an additional speed set-value to link a correction signal with the main
set-value in the arithmetic block (e.g. dancer position control, correction signal of
a synchronised system, correction signal via terminal during the assignment of the
main set-value via a serial interface, etc.). Adjustment is carried out when selecting
C025 = -3- and subsequent evaluation under C027 or C029.
