Advanced commissioning
6.7 Application-specific functions
Commissioning the extended service mode
Procedure
Proceed as follows to commission the essential service mode:
1. Interconnect a free digital input as signal source for the essential service mode.
Example, DI 3: Set p3880 = 722.3.
It is not permissible to interconnect the digital input to select the essential service mode
with other functions.
2. Using p3881, set the setpoint source for the essential service mode
Option 1:
– P3881 = 0: Last recognized setpoint (factory setting) or
– p3881 = 1: Fixed setpoint 15 or
– p3881 = 2: Analog setpoint or
– p3881 = 3: Fieldbus
Option 2:
– p3881 = 4: Technology controller
– Using p3884, set the source for the essential service mode setpoint.
3. Using p3882, set the source for the alternative setpoint.
– p3882 = 0: Last recognized setpoint (factory setting)
4. Parameterize the source to select the direction of rotation for the essential service mode.
Option 1: Extended service mode setpoint via p3881 = 0, 1, 2, 3:
Using p3883, invert the direction of rotation for the essential service mode. To do this,
interconnect p3883 with a digital input, e.g. with digital input 4 (DI4): Set p3883 = 722.4
The following applies:
– p3883 = 0 → normal direction of rotation in the essential service mode,
– p3883 = 1 → inverted direction of rotation in the essential service mode,
Option 2: Essential service mode via technology controller (p3881 = 4)
If you enter the setpoint for the essential service mode via the technology controller, then
the direction of rotation of the essential service mode setpoint is always valid.

If you cannot connect a setpoint in p3884, then the inverter takes technology setpoint
1 that has been connected (p2253).
p3882 = 1: Fixed speed setpoint which is defined in p1015
p3882 = 2: Maximum speed (value of p1082)
