7.1 Quick start Connections
7.1.1 Basic requirements
This section shows the basic connections which must be made for the drive to run in the
required mode. For minimal parameter settings to run in each mode please see the
relevant part of section 7.2 Quick Start / start-up on page 58.

Table 7-2 Minimum control connection requirements for each mode of operation
Ensure that no damage or safety hazard could arise from the motor starting
unexpectedly.
The values of the motor parameters affect the protection of the motor.
The default values in the drive should not be relied upon.
It is essential that the correct value is entered in Pr 0.46 Motor rated current. This affects
the thermal protection of the motor.
If the keypad mode has been used previously, ensure that the keypad reference has
been set to 0 using the buttons as if the drive is started using the keypad it will
run to the speed defined by the keypad reference (Pr 1.17).
If the intended maximum speed affects the safety of the machinery, additional
independent over-speed protection must be used.
