User Manual of EM760 High-Performance Inverter Where the input pulse frequency is subject to rapid change, or current system doesn’t have to make rapid response to the input pulse, the filter time can be prolonged appropriately for system stability. 6.5.4 High-speed digital output terminal (HDO) The EM760 series inverter supports high-speed pulse output (HDO) feature, which is similar to analog output. The only difference is that the output is in pulses of varying frequency instead of voltage. If high-speed pulse output is desired for Y2, set F03.07 as 1. Select high-speed pulse output feature via F03.23. Setting ofhigh-frequency pulse output: 100.0% output corresponds to the setting ofmax.
output frequency, and 0.0% the setting of min. output frequency. Anything therebetween is linear. F03.26 performs first-order inertia filtering on the output. 6.5.5 Virtual digital input terminal (VDI) The standard EM760 series inverter is equipped with eight virtual multi-function input terminals (VX1 to VX8), of which the functions and usages are basically the same as those of the actual input terminals. Differences are described below. For their similarities, refer to 6.5.1. 137 Function code Function codename Parameter description Unit Default setting Attribute F03.07 Options of Y2 output type 0: ordinary digital output 1:
