2.8 H: Terminal Functions
■
MFDI ON/OFF Time Delay
This function supplies an ON/OFF Delay to all MFDIs. To use this function, set parameters H1-61 to H1-67
[Terminal Sx On-Delay Time] and H1-71 to H1-77 [Terminal Sx Off-Delay Time].
WARNING! Crush Hazard. Make sure that the settings for H1-61 to H1-67 [Terminal Sx On-Delay Time] and H1-71 to H1-77
[Terminal Sx Off-Delay Time] are correct when you interface the drive with a safety process. The drive also applies the time delay
settings to the safety functions, for example, Emergency Override and Baseblock. Incorrect time delay settings can cause serious
injury or death from malfunction of the safety functions.
When the terminal is ON, the function set to that terminal activates after the ON-delay timer for the terminal is
expired. The terminal will reset the ON-delay timer when the terminal is OFF.
When the terminal is OFF and the function is active, the function will run until the OFF-delay timer is expired. The
terminal will reset the OFF-delay timer when the terminal is ON again.
The ON-delay and OFF-delay timers also have an effect on U1-10 [Input Terminal Status]. When the ON-delay is
expired and the function is active, the drive sets the applicable bits. When the OFF-delay is expired and the function
deactivates, the drive resets the bits.
Note:
The ON-delay timer does not apply when the inputs are ON at power-up.
Figure 2.46 shows drive operation when you apply ON/OFF-Delay Timers to the MFDI set for H1-xx = 6E [HAND
Command] in these conditions:
• S5-02 = 1 [HAND/AUTO Switchover During Run = Enabled]
• S5-04 ≠ 0 [HAND-OFF-AUTO Behavior ≠ Legacy]
Inverse Multi-Function Digital Inputs
For inverse MFDIs (H1-xx > 100), the delay timers use the inverse condition of the digital input.
When a terminal is OFF, the function set to that terminal activates after the ON-delay timer for the terminal is expired.
The terminal will reset the ON-delay timer when the terminal is ON.
When the terminal is ON and the function is active, the function will run until the OFF-delay timer is expired. The
terminal will reset the OFF-delay timer when the terminal is OFF again.
Note:
If you change a terminal function selection between an inverse and a non-inverse digital input selection while an ON-delay or OFF-delay
timer is active, the new delay timer will not go into effect until the current ON-delay or OFF-delay timer is expired, and the digital input
changes to ON or OFF.
