Description
PA4
Control mode
selection
0
The control mode of the driver can be set through this
parameter:
0: position control mode; 1: speed control mode;
2: trial run control mode; 3: JOG control mode.
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:
4 CNGP
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,

Refer to parameter PA12.
PA14
Input mode of the
position command

0
Set the input mode of the position command pulse; there
are following three modes which can be selected by setting
the parameter:
0: pulse + symbol;
1: positive rotation pulse / negative rotation pulse;
2: two orthogonal pulses inputs
