setting
External stop position setting
Can be set with any of the following.
(1) OPC-VG1-TL (T-link card) + Fuji MICREX
(2) OPC-VG1-DIOB (16-bit input, 10-bit output card)
(3) Standard RS-485
Internal stop position setting
Four points can be specified with the UNO function codes. The combination
of general-purpose input terminals switches between the four points.
Positioning repeatability
Within
±
1 pulse. (
±
0.088
°
when a pulse encoder of 1024 P/R is used)
The repeatability is dependent on the encoder pulse resolution and calculated
with 360
°
/4/encoder resolution.
When the encoder power is turned ON, the Z-phase detection operation
(initial operation) takes place.
Pulse encoder specifications
See Figure 6.2.8.
The encoder pulse resolution is selectable from: 128, 256, 512, 1024, 2048,
4096, 8192 P/R.
Opposing torque
Up to the maximum motor value is possible (under ASR PI control).
The displacement becomes large transiently relative to the momentary load
torque.
The speed control gain and orientation gain adjust the response of the
opposing torque.
Mechanical conditions The number of speed gear shifts is 4, which is changed with RT1 and RT2 .
