Only series “HVAC”:
Level inversion The function “Motor potentiometer” can be influenced through level inversion.
Example
- C114 = -3-
- Terminals E1 and E2 are level inverted. The function “Motor potentiometer” is then activated
according to the following table:
Function E1 E2
Setpoint = 0 Hz (T
iQSP
, C105) 1) HIGH HIGH
Reduce setpoint until f
dmin
(T
if
, C013) 2) LOW HIGH
Increase setpoint until f
dmax
(T
ir
, C012) HIGH LOW
Setpoint remains constant LOW LOW
1) HIGH level at terminals E1 and E2 reduce the setpoint via the QSP ramp (C105) until
f
d
= 0 Hz.
2) Only possible, if the setpoint has exceeded f
dmin
before.
Activation of the function “Motor potentiometer” via normally-open contacts.

- C007 = -26-
- The JOG value has priority over the function “Motor potentiometer”.
