(1) Preparation prior to servo parameter initialization
Before servo parameter initialization, check the following:
1. Servo motor model (Example:
ϒ 6/2000)
2. Amount of travel per m otor rotation (Example: 10 mm/motor
revolution)
3. Number of pulses per motor rotation (Example: 10000
pulses/motor revolution)
A detection unit is determined from 2 and 3.
Detection unit = (Amount of travel per motor rotation)/
(number of pulses per motor rotation)
(2) Procedure for servo param eter initialization
1. Turn on the power to the servo amplifier unit.
2. Turn on the power to the host controller in the emergency stop
state.
3. Perform parameter initialization from the host controller. Set
values for the parameters listed below. (See 5 to 10.)
Default
Parameter
number
Motor number None No.30
CMR 2 No.32
Numerator for the number of
pulses per revolution
10000 No.105
Denominator for the number of
pulses per revolution
1 No.106
Direction of travel 111 No.31
Reference counter capacity 10000 No.180
4. Set initialization bit DGPR to 0.
#7 #6 #5 #4 #3 #2 #1 #0
12 DGPR
When this bit is set to 0, a power disconnection request alarm
(alarm No. 0) is i ssued. However, 5 through 10 below can be set.
Start initialization (The power to the CNC is not turned on until 11.)
DGPR is automatically set to 1 when the
power is turned off then back on.
DGPR (b1) =0
