Setting Encoder Output Pulse - YASKAWA JUSP-MD D01A Series User Manual

5.3.7 Setting Encoder Output Pulse

Set the encoder output pulse using the following parameter.
Encoder Output Pulses
Pn212
Setting Range
16 to 1073741824
Pulses from the encoder per revolution are divided inside the multi-winding drive unit by the number set in
this parameter before being output.
Set the number of encoder output pulses according to the system specifications of the machine or host control-
ler.
Setting Range of Encoder Output
Pulses (P/Rev)
16 to 16384
16386 to 32768
32772 to 65536
65544 to 131072
131088 to 262144
Note 1. An encoder output pulse setting error (A.041) will occur if the setting does not satisfy the required conditions
listed in the table.
Pn212 = 25000 (P/Rev) is accepted, but
Pn212 = 25001 (P/Rev) is not accepted. The alarm A.041 is output because the setting unit differs from that in
the above table.
2. The upper limit of the pulse frequency is approximately 1.6 Mpps.
The servomotor speed is limited if the setting value of the encoder output pulses (Pn212) is large.
An overspeed of encoder output pulse rate alarm (A.511) will occur if the motor speed exceeds the upper limit
specified in the above table.
Output Example: When Pn212 = 16 (16-pulse output per one revolution), PAO and PBO are output as shown
