Start-up and control 83
Start the motor by pressing (the START key) to
activate the ID run.
Note: Both DRIVE ENABLE and LIFT RUN ENABLE
signals must be active.
10.80 LIFT RUN ENABLE
10.04 DRIVE ENABLE
ID run is indicated by alarm ID-RUN on the panel
display and by a rotating display on the 7-segment
display. Alarm: ID-RUN
7-segment display:
If the ID run is not successfully completed, fault ID-
RUN FAULT is generated. Fault: ID-RUN FAULT
Speed measurement with encoder
Encoder feedback can be used for more accurate motor control.
• Asynchronous motors: Optional
• Permanent magnet motors: Mandatory
Follow these instructions when encoder interface module FEN-xx is installed in drive option
Slot 1 or 2.
Select the encoder to be used. For more information,
see parameter group
90 ENC MODULE SEL on page
268 .
90.01 ENCODER SEL
Set other necessary encoder parameters:
• Absolute encoder parameters in group 91 (typically
set parameters 91.01 SINE COSINE NR, 91.02
ABS ENC INTERF, and 91.04 POS DATA BITS).
• Pulse encoder parameters in group 93 (typically
set parameter 93.01 ENC PULSE NR).
91.01 … 91.20
93.01 … 93.09
Save new parameters settings into the permanent
memory by setting parameter
16.05 PARAM SAVE to
value Save .
16.05 PARAM SAVE
Set parameter 90.06 ENC PAR REFRESH to
Configure so that the new parameter settings take
effect.
90.06 ENC PAR REFRESH
Safe torque off
The Safe torque off function disables the control voltage of the power semiconductors of the
drive output stage, thus preventing the inverter from generating the voltage required to rotate
the motor. For safe torque off wiring, see chapter
The Safe torque off function on page 333 .
If there is a safe torque off circuit in use, check that
the circuit functions.
Select how the drive reacts when the Safe torque off
function is active (that is, when the control voltage of
the power semiconductors of the drive output stage is
disabled).
