5. PARAMETERS
(1) For output pulse designation
Set " 0 " (initial value) in parameter No.PC03. When parameter No.PC03 has been set to " 1
the parameter error (37) occurs.
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 A B-phase output pulses are as indicated
below.
A B-phase output pulses
(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.
Resolution per servo motor revolution
Output pulse
For instance, set "8" to Parameter No.PA15, the actually output A/B-phase pulses are as indicated below.
A B-phase output pulses
(3) For output electronic gear ratio setting
Set " 3 " in parameter No.PC03.
The resolution per servo motor revolution is set by parameter No.PA15, PA16.
Output pulse Resolution per servo motor revolution
For instance, set "3" to Parameter No.PA15 and "32" to Parameter No.PA16, the actually A B-phase
output pulses are as indicated below.
