Settings: MENU – Settings – Control Settings
Switching between CW/CCW (factory setting: no)
• Yes: Switching between CW/CCW rotation by means of the CW/CCW key
possible in LOCAL mode
• No: The CW/CCW key has no effect in LOCAL mode
For safety reasons, the CW/CCW key is disabled in the factory setting (pumps and
fans must normally only be operated in one direction).
In the operation status in LOCAL mode, the current direction of rotation is indicated
by an arrow next to the operating mode.
6.2.3.5 Jog (reserved for future use)
6.2.3.6 Increase Setpoint / Decrease Setpoint
You can use the “increase” and “decrease” keys to set the setpoint with a
resolution of 1 % of the maximum speed.
(e.g. if the resolution is 15 min
-1
at p1082 = 1500 min
-1
)
You can also enter the setpoint numerically. To do so, press F2 in the operation
screen. The system displays an inverted edit field for entering the required speed.
Enter the required value using the numeric keypad. Press F5 OK to confirm the
setpoint.
When you enter values numerically, you can enter any speed between the
minimum speed (p1080) and the maximum speed (p1082).
Setpoint entry in LOCAL mode is unipolar. You can change the direction of rotation
by pressing the +/- keys (see Section 6.2.3.4).
