Data
attribute
A
Set value Indicated item Description
0 Normal state Indicates "" during Servo-OFF, and "00" during Servo-ON.
1
Mechanical angle Indicates a value between 0 and FF hex.
The value 0 indicates the zero position of encoder.
The value increments when the motor rotates in counter clockwise (CCW)
direction.
The value returns to 0 when it exceeds FF, but the count continues.
When an incremental encoder is used, it indicates "nF" (i.e., not
fixed) until the zero position of the encoder is detected after the
control power is on.
2
Electric angle Indicates a value between 0 and FF hex.
The value 0 indicates the position when the U-phase electro-
motive force shows the positive peak.
The value increments when the motor rotates in counter clockwise (CCW)
direction.
The value returns to 0 when it exceeds FF, but the count continues.
3
Cumulative count of
MECHATROLINK-II
communications errors
*1
Indicates a value between 0 and FF hex.
The cumulative count is saturated when it reaches the
maximum value (FFFF hex).
In this case, only the lowest order byte is shown.
The value returns to 00 when it exceeds FF, but the count continues.
4
Rotary switch setting
(node address)
Indicates the rotary switch setting (i.e. node address) read at
power-on. The indication is in decimal.
The value is not altered by any changes on the rotary switch
setting after the power-on.
5
Cumulative count of
encoder communications
errors
*1
Indicates a value between 0 and FF hex.
The cumulative count is saturated when it reaches the
maximum value (FFFF hex).
In this case, only the lowest order byte is shown.
The value returns to 00 when it exceeds FF, but the count continues.
6
Cumulative count of
external encoder
communications errors
*1
7
Z-phase counter
*2
Indicates the Z-phase count value read from the external
encoder when an incremental external encoder is used during
full closing control. The value between 0 an FF hex is indicated.
8 or over Unused Do not set anything.
*1. The cumulative count of communication errors is cleared when the control power is cut off.
*2.The value read from the encoder is indicated directly, regardless of the External Feedback Pulse
Direction Switching on the Pn326.
