6.2 Basic operation - Quick start guide
... with ControlBox (Option: SK TU2-CTR)
The simplest procedure to prepare the frequency inverter for operation is described below. For this operation,
jog frequency (P113) is used. Only one parameter needs to be changed in the standard setting.

Key
Display
1.
Connect the power supply to the frequency inverter. The operating display
changes to the "Operational" mode.
2.
-Keep pressing the
key until menu group P 1 _ _ is displayed.
3.
-Press the
key to access the Basis Parameter menu group.
4.
Press the
key. Parameter No. P101 and the following will be displayed.
5.
Press the
key until parameter P113 >jog frequency< is displayed.
6.
Press the
key to display the actual frequency setpoint (standard factory
setting = 0.0Hz).
7.
Press the
key to set the required frequency setpoint (e.g. 35.0Hz).
8.
Press the
key to store the setting.
9.
Keep pressing the
key until the operating display is reached.
Or press
and
simultaneously to change directly to the operation
display.
Use the
key to switch on directly; the frequency inverter then changes
directly to the operating display.
10.
Switch on the frequency inverter using the
key.
The motor shaft starts up and indicates that the inverter output frequency is
reaching the setpoint of 35Hz.
Note:
The setpoint value is reached after 1.4 seconds (35Hz / 50Hz x 2s). The
standard start-up time is 2 seconds to reach 50Hz (as defined by P102 and
P105).
If necessary, the motor speed (i.e. the frequency) can be adjusted directly
using the
keys. By pressing the
key, the new set value can be
saved directly in P113.
11.
Switch off the frequency inverter using the
key.
The motor is braked and is brought to a controlled stop (this takes 1.4
seconds). The standard deceleration time is 2 seconds from 50Hz to standstill
(defined by P103, P105).
Note:
The inverter always supplies 0Hz for 0.5 seconds after stopping (P559, >DC-
Time lag<). If there is a new enable during this period, then this is interrupted.
