Setting Encoder Output Pulse - YASKAWA SGDV 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 SERVOPACK by the number set in this parame-
ter before being output. Set the number of encoder output pulses according to the system specifications of the
machine or host controller.
According to the encoder resolution, the number of encoder output pulses are limited.
Setting Range of
Encoder Output
Pulses (P/Rev)
16 to 16384
16386 to 32768
Note 1. An encoder output pulse setting error (A.041) will occur if the setting is outside the allowable range or does not
satisfy the setting conditions.
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 approx. 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
