3.4 PARAMETER INITIALIZATION
(1) Preparation prior to servo parameter initialization
Before servo parameter initialization, check the following information:
1. Servo motor model (Example: β 8/3000is)
2. Amount of travel per motor revolution (Example: 10 mm/motor revolution)
At first, decide "detection unit", for example detection unit = 1um.
Next, calculate number of pulses per motor revolution with "detection unit" and "amount
of travel per motor revolution" by the following formula.
(Number of pulses per motor revolution)
= (Amount of travel per motor revolution) / (Detection unit)
Example)
In case detection unit = 1um, amount of travel per motor revolution =10mm
10mm/1um=10000
Then, number of pulses per motor revolution = 10000 pulses/revolution
(2) Procedure for servo parameter initialization
1. Turn on the servo amplifier unit.
2. Turn on the host controller in the emergency stop state.
3. Perform parameter initialization from the host controller. Set values for the
parameters listed below. (See the following procedure No.5 to No.9.)
