• Set the parameters so that the result calucurated by multiplying the command pulse by the
electronic gear ratio does not exceed 175 Mpps
If it exceeds 175 Mpps
Example:
When using an incremental encoder (resolution: 1,048,576):
If the electronic gear ration is 500 (Pn008 = 500) and the command pulse value is 100 kpps,
100 kpps x 1,048,576/500 = 209,715,200 = 209.7152 Mpps.
This exceeds 175 Mpps
If the electronic gear ration is 5,000 (Pn008 = 5,000) and the command pulse value is 100
kpps,
100 kpps x 1,048,576/5,000 = 20,971,520 = 20.97152 Mpps.
This does not exceed 175 Mpps
*1 Alarm No. 27.2 will occur if 3 Gpps is exceeded when using software version 1.10 or higher. The software
version can be checked on the front panel or with the CX-Drive. For information on checking the software
