7 Running the motor
This chapter takes the new user through all the essential steps to
running a motor for the first time.
7.1 Quick start Connections
7.1.1 Basic requirements
This section shows the basic connections which must be made for the
drive. For minimal parameter settings to run, please see the relevant part
of section 7.2 Quick Start set-up on page 64.
Table 7-1 Minimum control connection requirements for each
control mode
Table 7-2 Minimum control connection requirements
Speed and position feedback
Suitable devices are:
• Incremental encoder (A, B or F, D with or without Z) with
commutation signals (U, V, W)
• Incremental encoder with forward and reverse outputs (F, R with or
without Z) and commutation outputs (U, V, W)
• SINCOS encoder (with Stegmann Hiperface, EnDat or SSI
communications protocols)
• EnDat absolute encoder
For Solutions Module terminal information see section 12.15 Menus 15
and 16: Solutions Module set-up on page 159 or the appropriate
Solutions Module Option User Guide.
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.
