Hey guys,
I'm working on a machine for a customer using a servo. I'm pulsing the servo using the PLSY instruction. In order to acheive the customer's desired cycle time, I've increased a few of my output pulses to 30,000Hz. The manual states that the allowable frequency range is 2-20,000 Hz for the FX2N. 30,000 seems to work fine but 40,000 did not work at all. Will running at 30,000 Hz damage the secondary processor on the PLC? I believe that there is a 2nd onboard processor just for the PLSY intstruction.
I'm also confused as to why the FX2N has much less functionality than the FX1N. The FX1N series has about 6 different types of pulsing instructions with frequency ranges up to 1 million Hz. The FX2N has 1 pulsing instruction and the stated frequency range is 2-20KHz and you can only use this intsruction once throughout the entire program. Makes no sense to me, the higher end model getting less functionality.
