Description
PA12
Numerator
of position
command
pulse ratio
2
Set the ratio of the position command pulse (electronic gear).
Under position control mode, with the setting of the PA12 and
PA13, it is convenient to match with pulse source of each
type, which can reach users‟ perfect control resolution (that is
angle/pulse).
Expression:

P
P: pulse amount of the input command;
G: electronic gear ratio, G=ratio numerator / ratio
denominator.
N: circle number that the motor rotates;
C: each circle line number of photo electricity encoder,
C of our system =2500.
E.G.: input command pulse with number of 6000 to make the
servo motor rotate one circle,

So set PA12 as 5 and PA13 as 3.
We recommend the range of electronic gear ratio as:

Refer to parameter PA12.
PA14
Input mode
of the
position
command
pulse
0
Set the input mode of the position command pulse; there are
following three modes can be selected by setting the
parameter:
0: pulse + symbol;
1: positive rotation pulse / negative rotation pulse;
2: two orthogonal pulses inputs
Default setting is 0: pulse + symbol, negative logic.
PA20
Invalid
input on the
end of the
stroke
1
0: Valid stroke end of LSP, LSN positive rotation, negative
rotation.
When switch LSP is connected, driving of the positive rotation
is allowed; When switch LSP is disconnected, driving of the
positive rotation is prohibited (torque of the positive direction
is 0). LSN is the same as LSP. If LSP and LSN are both
disconnected, the abnormal alarming of driving prohibited will
occur (NO.7).
