5.3.7

Setting Encoder Output Pulse

Set the encoder output pulse using the following parameter.
Pn212
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.
Setting Range of Encoder Output
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
2. The upper limit of the pulse frequency is approximately 1.6 Mpps.
Output Example: When Pn212 = 16 (16-pulse output per one revolution), PAO and PBO are output as shown

16 to 1073741824
Pulses (P/Rev)
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.
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.
