5. PARAMETERS
5 - 9
(1) For output pulse designation
Set " 0 " in parameter No.PC03.
Set the number of pulses per servo motor revolution.
Output pulse set value [pulses/rev]
For instance, set "5600" to Parameter No.PA15, the actually output A/B-phase pulses are as indicated
below.
A/B-phase output pulses 1400 [pulse]
5600
4
(2) For output division ratio setting
Set " 1 " in parameter No.PC03.
The number of pulses per servo motor revolution is divided by the set value.
Output pulse
[pulses/rev]
Resolution per servo motor revolution
Set value
For instance, set "8" to Parameter No.PA15, the actually output A/B-phase pulses are as indicated below.
A/B-phase output pulses 8192 [pulse]
262144
8
1
4
(3) A/B-phase pulse electronic gear setting
This parameter is made valid when parameter No.PC03 is set to " 3 ".
Set the encoder pulses (A/B-phase) output by the servo amplifier.
Set the encoder pulses output by the servo amplifier by parameter No.PA15 and parameter No.PA16.
Travel distance [pulse] of the linear encoder is multiplied by the set value.
Output pulse Travel distance of linear encoder [pulse]
Set value of parameter No.PA15
Set value of parameter No.PA16
The number of A/B-phase pulses actually output is 1/4 times greater than the preset number of pulses. Also,
the maximum output frequency is 4.6Mpps (after multiplication by 4). Use this parameter within the range.
When the set value is "0 (factory setting)", it is internally treated as "1".
