GR3 Encoder Output Pulse Number Communication Addr.: 012EH
Default: 1 Related Section: N/A
Applicable Control Mode: ALL
Unit: pulse
Range: 1 ~ 125 (with B=0)
10020 ~ 12500 (with B=1)
Settings:
A
B
This parameter is used to set the pulse numbers of encoder outputs per motor revolution.
ASDA-A series:
A: Range of the pulse numbers or the pulse dividing ratio of the encoder outputs
• Range of the setting value: 1 ~ 125 (with B=0) or 20 ~ 2500 (with B=1)
B: Pulse dividing ratio function selection
• When B=0, the setting value A represents the pulse dividing ratio, which is equal to 2500/A.
At this time, the range of the setting value A is 1 ~ 125.
For example:
If A=2 and B=0, i.e. P1-46 is set to 2, the pulse dividing ratio is equal to 2500/2 = 1250.
It indicates that the pulse numbers of encoder outputs per motor revolution = 1250 pulses
(The encoder will output 1250 pulses per motor revolution)
If A=5 and B=0, i.e. P1-46 is set to 5, the pulse dividing ratio is equal to 2500/5 = 500.
It indicates that the pulse numbers of encoder outputs per motor revolution = 500 pulses
(The encoder will output 500 pulses per motor revolution)
• When B=1, the setting value A directly represents the pulse numbers of encoder outputs per
motor revolution. At this time, the range of the setting value A is 20 ~ 2500.
If A=1250 and B=1, i.e. P1-46 is set to 11250, the pulse numbers of encoder outputs per
motor revolution = 1250 pulses (The encoder will output 1250 pulses per motor revolution)
If A=500 and B=1, i.e. P1-46 is set to 10500, the pulse numbers of encoder outputs per
motor revolution = 500 pulses (The encoder will output 500 pulses per motor revolution)
ASDA-A+ series:
A: Range of the pulse numbers or the pulse dividing ratio of the encoder outputs
• Range of the setting value: 1 ~ 125 (with B=0) or 20 ~ 2500 (with B=1)
B: Pulse dividing ratio function selection
• When B=0, the range of the setting value A is 1 ~ 125, the pulse numbers of encoder outputs
per motor revolution =
