selfbuilding Posted February 22, 2011 Report Share Posted February 22, 2011 Hi!! We have an application that involves an M91-2-UN2. We hope to use the HSC function reset (Hardware configuration). Digital input I2 apply the counting pulses (360 pulses per revolution) and the I3 to the reset, all square signals, taking the signal off and on the same duration. The shaft moves in one direction only. The problem is that the reset signal ( I3 ) is not resetting the counter in less than 6 ms, but the count signal (I2) are being counted strictly accurate about 10kHz. Correct if wrong: With 60 revolutions per minute a reset and count pulse have approximately 1.4 ms. UN2 manual says the minimum pulse of HSC is 40us. We also can not enable the SB10, and do not create any software in ladder, just configure the "hardware configuration", download to the OPLC and observe the counter MI in Debug Mode.
