Output Signal On/Off Delay Function - Hitachi WJ200 Series Instruction Manual

Output Signal ON/OFF Delay Function

Intelligent outputs including terminals [11], and the output relay, have configurable
signal transition delays. Each output can delay either the OFF-to-ON or ON-to-OFF
transitions, or both. Signal transition delays are variable from 0.1 to 100.0 seconds.
This feature is useful in applications that must tailor inverter output signals to meet
timing requirements of certain external devices.
The timing diagram below shows a sample output signal (top line) and the results of
various ON/OFF delay configurations.
• Original signal - This example signal waveform consists of three separate pulses
named "A," "B," and "C."
• ...with ON delay - Pulse A is delayed by the duration of the ON delay time. Pulses B
and C do not appear at the output, because they are shorter than the ON delay.
• ...with OFF delay - Pulse A is lengthened by the amount of the OFF delay time. The
separation between pulses B and C does not appear at the output, because it is
shorter than the OFF delay time.
• ...with ON/OFF delays - Pulse A is delayed on both leading and trailing edges by the
amounts of the ON and OFF delay times, respectively. Pulses B and C do not appear
at the output, because they are shorter than the ON delay time.
