F2036 Excessive position feedback difference

Parameters for encoder 2 incorrect
Mechanical system between motor shaft and
encoder 2 incorrectly parameterized
Mechanical system between motor shaft and
encoder 2 is not rigid (e.g. gear play, slip) and
monitoring window is too small
Encoder cable defective
Maximum input frequency of encoder interface
Encoder 2 was not mounted to driven axis
Incorrect encoder gear settings
Position data reference of an absolute encoder
LSA Control S.L. www.lsa-control.com comercial@lsa-control.com (+34) 960 62 43 01
Supported by Firmware Variant:
In cyclic operation the difference between actual position value 1 and
position value 2 (see also P-0-0391, Actual position value difference
encoder1 - encoder2) is compared to S-0-0391, Monitoring window
feedback 2. If the absolute value of the difference is greater than the
monitoring window and both encoders have been homed, the error F2036
is generated.
The drive carries out the error reaction parameterized in P-0-0119, Best
possible deceleration and the reference bits of both encoders are
cleared (S-0-0403, Position feedback value status).
The monitoring function is inactive if the value "0" was entered
in the S-0-0391, Monitoring window feedback 2 parameter.
Check S-0-0115, Position feedback 2 type and
S-0-0117, Feedback 2 Resolution
Check S-0-0121, Input revolutions of load gear,
S-0-0122, Output revolutions of load gear, and
S-0-0123, Feed constant
Increase S-0-0391, Monitoring window feedback 2,
switch off in the case of gear with slip
Replace encoder cable
Reduce velocity
Set S-0-0391, Monitoring window feedback 2 to "0"
(switch monitoring function off)
Check relevant encoder parameters and correct them, if
P-0-0121, Gear 1 motor-side (motor encoder) /
P-0-0122, Gear 1 encoder-side (motor encoder)
P-0-0124, Gear 2 load-side (optional encoder) /
P-0-0125, Gear 2 encoder-side (optional encoder)
S-0-0121, Input revolutions of load gear / S-0-0122,
Output revolutions of load gear
Execute P-0-0012, C0300 Command Set absolute
