9 Running the motor
This chapter takes the new user through all the essential steps to
running a motor for the first time, in each of the possible operating
modes.
For information on tuning the drive for the best performance, see
Chapter 10
Optimization
.
9.1 Quick start Connections
9.1.1 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 9.4
Quick Start
commissioning/start-up
on page 128.
Table 9-1 Minimum control connection requirements for each
control mode
Table 9-2 Minimum control connection requirements for each
mode of operation
Speed feedback
Suitable devices are:
•
Incremental encoder (A, B or F, D with or without Z)
•
Incremental encoder with forward and reverse outputs (F, R with or
without Z)
•
SINCOS encoder (with, or without Stegmann Hiperface, EnDat or
SSI communications protocols)
•
EnDat absolute encoder
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

16 and 17: Solutions Module set-up

Solutions Module option user guide.
9.2 Changing the operating mode
Changing the operating mode returns all parameters to their default
value, including the motor parameters. (Pr
0.49
and Pr
0.34
are not
affected by this procedure.)
Procedure
Use the following procedure only if a different operating mode is
required:
1. Enter either of the following values in Pr
xx.00
, as appropriate:
1253 (EUR, 50Hz AC supply frequency)
1254 (USA, 60Hz AC supply frequency)
2. Change the setting of Pr
0.48
as follows:
The figures in the second column apply when serial communications are
used.
3. Either:
•
Press the red
reset button
•
Toggle the reset digital input
•
Carry out a drive reset through serial communications by setting Pr
10.38
to 100 (ensure that Pr.
xx.00
returns to 0).
9.3 Changing keypad mode
Pressing the following keypad buttons selects the keypad mode
•
Blue - Auto
•
Red
- Off
•
Green - Hand
In Hand mode, the motor speed is adjusted by pressing the keypad up/
down arrow buttons.
In Auto mode, the motor speed control reference is determined by the
value set in the speed/frequency reference selector Pr
0.05
. If hand
mode is selected then the motor speed will not change during the
transition.
In Off mode, the motor will be stopped but pressing the keypad up/down
arrow buttons will allow the keypad control reference Pr
1.17
to be
adjusted. Selecting Hand mode will then ramp the motor up to the
selected speed.
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
0.35
).
If the intended maximum speed affects the safety of the
machinery, additional independent over-speed protection
must be used.
