Monitoring And Application; Encoder Sim. Resolution; Feedback Signal Monitoring - Danfoss VLT AutomationDrive Programming Manual

Parameter Descriptions
Usually the resolver feedback is used as motor feedback
from permanent magnet motors with 1-01 Motor Control
Principle set to Flux with motor feedback.
Resolver parameters cannot be adjusted while the motor is
running.
17-50 Poles
Range: Function:
2 [2 - 2 ] Set the number of poles on the resolver.
*
The value is stated in the data sheet for resolvers.
17-51 Input Voltage
Range: Function:
7.0 V [2.0 - 8.0 V] Set the input voltage to the resolver. The
*
voltage is stated as an RMS value.
The value is stated in the data sheet for
resolvers.
17-52 Input Frequency
Range:
10.0 kHz [2.0 - 15.0
*
kHz]
17-53 Transformation Ratio
Range: Function:
0.5 [0.1 - 1.1 ] Set the transformation ratio for the resolver.
*
The transformation ration is:
V Out
T ratio =
The value is stated in the data sheet for
resolvers.

17-56 Encoder Sim. Resolution

Set the resolution and activate the encoder emulation function
(generation of encoder signals from the measured position from
a resolver). Needed when necessary to transfer the speed or
position information from one drive to another. To disable the
function, select [0].
Option:
[0] Disabled

17-59 Resolver Interface
Activate the MCB 103 resolver option when the resolver
parameters are selected.
To avoid damage to resolvers, 17-50 Poles – 17-53 Transformation
Ratio must be adjusted before activating this parameter.
Option:
[0] Disabled
*
[1] Enabled

3.18.4 17-6* Monitoring and Application

This parameter group is used for selecting additional
functions when the MCB 102 Encoder option or MCB 103
Resolver option is fitted into option slot B as speed
feedback.
Monitoring and application parameters cannot be adjusted
while the motor is running.
17-60 Feedback Direction
Change the detected encoder rotation direction without
changing the wiring to the encoder.
Option:
[0] Clockwise
*
[1] Counter clockwise
NOTE!
This parameter cannot be adjusted while the motor is
running.

17-61 Feedback Signal Monitoring

Select which reaction the Adjustable frequency drive should take
if a faulty encoder signal is detected.
The encoder function in 17-61 Feedback Signal Monitoring is an
electrical check of the hardware circuit in the encoder system.
Option:
[0] Disabled
