Number Parameter Min Max Default Note
7.3.1.1 Pulse/revolution 1 65535 1024
7.3.1.2 Invert direction 0 1 0
0 = No
1 = Yes
7.3.1.3 Reading rate 0 4 1
Time used to calculate speed actual value.
NOTE: Use value 1 in Closed Loop mode.
0 = No
1 = 1 ms
2 = 5 ms
3 = 10 ms
4 = 50 ms
7.3.1.4 Encoder type 1 3 1
1 = A,B = speed
2 = A = REF, B = DIR
3 = A= FORW, B = REV
1 = A, B = Speed
Only with this input type it is possible to use Closed Loop speed control in an NXP
drive. NXS drives do not have Closed Loop possibility, but encoder signal can be
used e.g. for reference or positioning.
This input mode requires that both channels A and B are receiving pulses, differen-
tial connection is recommended.
Direction of speed is determined from 90° difference in signals.
2 = A = Ref, B = Dir
This type cannot be used for Closed Loop control!
In this mode only channel A is receiving pulses. Channel B will determine if direc-
tion is negative or positive. Input in channel B must be static signal.
