Encoder Pulse Number; Encoder Channel Swap / Direction; Encoder Sample Time - KEB COMBIVERT F5 Instruction Manual

Parameter Description - Encoder Set Up
Encoder pulse number
Encoder channel swap /
direction
Encoder sample time
Unit:
Value range:
Default setting:
Adjustment value:
c
If the incremental encoder pulse number is not
correctly adjusted, the elevator drive can run very
slowly, or over-speed is possible or other unforeseen
conditions may occur. Therefore, it is absolutely
necessary to adjust this parameter correctly.
This parameter can be used to swap the two encoder channels, reverse
the direction of the entire system, or both swap encoder channel and
reverse the system direction. See also section 5.11.4
Unit:
Value range:
Default setting:
Adjustment value:
This parameter is used to adjust the sample time of the encoder
feedback for calculation of the actual motor speed value. With certain
motors or encoders it may be beneficial to use a time other than the
factory setting. Lower values lead to higher bandwidth and faster
response times of the motor. However lower values also increase
the systems susceptibility to electrical noise on the encoder signal.
Therefore on some systems having higher noise levels, lower values
may not be suitable. If this electrical noise is a problem, the motor will
produce an audible noise while running.
Unit: -
Value range: 0_5, 1, 2, 4 , 8, 16, 32 mSec
Default setting: 4 mSec
Adjusted value: based on application requirements
Example: with a 4 mSec sample time the resulting speed measurement
resolution using a 1024 encoder is +/-3.5 rpm. A setting of 8 mSec
gives +/-1.8 rpm.
With Sin/Cos, Hiperface, EnDat encoders see also parameter LF.76
for extended resolution adjustments.
