ASDA-A2 Chapter 7 Motion Control
7-34 Revision February, 2017
Setting Method
P1-44: numerator
P1-45:
denominator
 If the pulse number of slave axis is L, the motor axis operates
R cycle.
Then, the setting of gear ratio is P1-44/P1-45＝1280000 x R /
L
 The gear ratio of PT and PR is the same.
 Digital Output of E-cam, the description is as follows:
DO Name and
Number
 DO.CAM_AREA (DO no.= 0x18)
Function
 If DO.CAM_AREA is ON, it means the position of E-cam axis
is in the setting range.
When the E-cam is
engaging
 Set the angle range of DO ON by P5-90 and P5-91.
 Please refer to table 1 and 2 below
When the E-cam is
disengaging
 DO.CAM_AREA is OFF.
Table 1 P5-90 <= P5-91:
E-Cam angle 0° ~ P5-90 ~ P5-91 ~ 360°
DO:CAM_AREA OFF OFF ON ON ON OFF OFF
Table 2 P5-90 > P5-91:
E-Cam angle 0° ~ P5-91 ~ P5-90 ~ 360°
DO:CAM_AREA ON ON OFF OFF OFF ON ON
7.11.1 Function Description of CAPTURE (Data Capture)
The concept of CAPTURE is to capture the position of motion axis instantaneously by using the
external trigger signal DI7. Then save it in data array so as to be used for motion control
afterwards. Since CAPTURE is finished by hardware, there is no problem of software delay. It
also can accurately capture the high-speed motion axis. The CAPTURE features provided by this
servo drive is as follows.
CAPTURE Features
Pulse Source
 Main encoder of the motor
 Auxiliary encoder (linear scale)
 Pulse command
The selected axis will be displayed in P5-37, the default value can be
written in before capture.
Note: When the source of COMPARE is CAP axis, the CAP source
cannot be changed.
Trigger signal
 Triggered by DI7, the response time is 5 usec.
Note: DI7 directly connects to CAPTURE hardware. Thus, regardless
the setting value of P2-16 (DI Code), CAPTURE can work. When
using CAPTURE, in order to avoid DI error, system will force to
disable DI function, which means the setting will be P2-16 =
0x0100 automatically. Since the value is not written into
EEPROM, P2-16 will return to the default value after re-power on.
