7.5.14.3 Change of the direction of rotation (CW/CCW)
Not failsafe change of the direction of rotation
Function Settings
C007 = -0- ... -13-, or
C007 = -0- ... -13-, -23-, -43-, -45- (only series “HVAC”)
enable the change of the motor direction via terminal E4.
The change depends on
- the set times T
ir
(C012) and T
if
(C013),
- the connected ramp function generator S-shape (C182). (Series “HVAC”)
Adjustment When connecting the controller in phase
- a CW field of rotation will occur at LOW signal,
- a CCW field of rotation will occur at HIGH level.
Series “HVAC”: The signal levels are indicated for C114 = -0- (see chapter 7.5.14.1).
Important - In the event of wire breakage or a failure of the external voltage supply, the direction of rotation
can be changed.
- CW/CCW changeover only in the main setpoint.
Failsafe change of the direction of rotation
Function Settings
C007 = -14- ... -22-, or
C007 = -14- ... -22-, -34-, -47- (only series “HVAC”)
enable the failsafe change of the direction of rotation via terminals E3 and E4.
The change depends on
- the set times T
ir
(C012) and T
if
(C013),
- the connected ramp function generator S-shape (C182). (Series “HVAC”)
Adjustment Function E3 * E4 *
CCW rotation LOW HIGH
CW rotation HIGH LOW
Quick stop LOW LOW
Unchanged HIGH HIGH
* Series “HVAC”: The signal levels are indicated for C114 = -0- (see chapter 7.5.14.1).
Important - If a HIGH signal is assigned to terminals E3 and E4, the terminal signal which was activated first
determines the direction of rotation.
- If a HIGH signal is assigned to terminals E3 and E4 when connecting the mains, the controller
will activate the quick stop function.
- CW/CCW changeover only in the main setpoint.
- For speed control with actual value feedback, the CW/CCW changeover is not possible.
