Connector Description
Limitation bits
K0810
The meaning of these bits is described in Section 11, Parameter List, under
parameter r040.
Connectors for raw data of pulse encoder evaluation
Measuring time for speed evaluation of pulse encoder
K0910
1 corresponds to 41.6666 ns if K0912 = xxxx xx0x (divisor 1:1)
1 corresponds to 83.3333 ns if K0912 = xxxx x01x (divisor 1:2)
1 corresponds to 166.666 ns if K0912 = xxxx x11x (divisor 1:4)
This value is always slightly higher than the measuring time set in P147.
Number of pulses during measuring time set in K0910
K0911
The speed of the pulse encoder can be calculated from connectors K0910,
K0911 and K0912 by the following equation:
=
n [ rev / ] s
act
Pulse number of encoder = 1*P141,
if K0912 = xx0x xxxx (1x evaluation)
Pulse number of encoder = 2*P141,
if K0912 = x01x xxxx (2x evaluation)
Pulse number of encoder = 4*P141,
if K0912 = x11x xxxx (4x evaluation)
Meas. time = 1* K0910 if K0912 = xxxx xx0x (divisor 1:1)
Meas. time = 2* K0910 if K0912 = xxxx x01x (divisor 1:2)
Meas. time = 4* K0910 if K0912 = xxxx x11x (divisor 1:4)
K0912 Status of speed evaluation of pulse encoder
xxxx xxx0 = asynchronous measurement
xxxx xxx1 = (gating-pulse-)synchronized measurement
xxxx xx0x = divisor 1:1
xxxx x01x = divisor 1:2
xxxx x11x = divisor 1:4
xxx0 0xxx = pulse encoder type1
xxx1 0xxx = pulse encoder type1a
xxx0 1xxx = pulse encoder type2
xxx1 1xxx = pulse encoder type3
xx0x xxxx = 1x evaluation
x01x xxxx = 2x evaluation
x11x xxxx = 4x evaluation
0xxx xxxx = No pulse encoder error
1xxx xxxx = Pulse encoder signal states occurred during the measurement
which may not occur on a rotating pulse encoder. They indicate a signal
short circuit or an interruption in a pulse encoder signal.
When the pulse encoder is stationary or oscillating around one position,
signal states of this type are perfectly normal and do not indicate a signal
fault.
