1. D1is the distance between two Z phase signals that are close tegether of servo motor
ECNODER.
2. D2 is the distance between the HOME DOG input points to the servo axis by using the
1 st gear speed decelerating stop. The calculating formula is as following:
D2 ≒ servo lag + deceleration distance ≒

K p is the servo position loop gain (sec -1 ), , T a is the servo axis G00
acc/decelerating time.
If the length between the Home DOG input point and the disappear point is smaller
than D2, then warning message (MOT 0027 Home DOG length is too short) will occur.
3. D3 is the traveling distance at the time when servo motor starts from complete stop and
accelerates to 2 nd gear speed to when Home DOG singnal disappears. In order to
catch the Z phase signal under the condition of the same speed, the distance of D3
must be long enough in order for the servo motor to be able to reach the 2 nd gear
speed. Calculating formula is as following:
D3 ≧
