CHAPTER 2 WIRING
Parameter setting
To assign pulse command inhibit to a sequence input terminal, specify the corresponding value
("26") to the input terminal function setting parameter.
2
Command pulse ratio 1: Sequence input signal (Reference value 27)
Command pulse ratio 2: Sequence input signal (Reference value 28)
Use the parameters to change the multiplication of the command input pulse under position
control in the extension mode.
These functions are enabled only if "6" (extension mode) or "7" (positioning operation) is selected
for parameter PA1_01.
Function
To perform pulse operation in the extension mode (mode compatible with conventional α Series),
be sure to assign command pulse ratio 1 or command pulse ratio 2 to a CONT input signal.
Turn servo-on, position control and command pulse ratio 1 (2) on to enable pulse operation.
If command pulse ratio 1 is turned on, the ratio set at PA2_54 (command pulse ratio 1) is enabled.
If command pulse ratio 2 is turned on, the ratio set at PA2_55 (command pulse ratio 2) is enabled.
The result of the following equation becomes the encoder-equivalent pulse.
(Number of input pulses) x ((Numerator 0 to 3 of electronic gear ratio)/(Denominator of electronic
gear ratio)) x Command pulse ratio
Parameter setting
To assign command pulse ratio 1/2 to a sequence input terminal, specify the corresponding
number ("27" or "28") to the input terminal function setting parameter.
