Push-Button (PB) Switch – Normally Open (NO)
Some options:
Latched Start
can be configured using terminal 18 only.
Reset
can be accomplished from a remote location when the drive trips.
Jog
can also be accomplished with a push-button NO switch. The Jog
frequency is set by parameter 213 and the ramp to the jog frequency
is set by parameter 211.
Note that the opposite side of the switch goes to terminal 12 which is a source of +24Vdc.
When the PB is pressed, and +24V is seen at the Digital Input, the programmed command,
such as Jog, is activated. When the PB is released and 0Vdc is seen at the Digital Input the
command is removed.
Jog Command is set in Parameter 305 for terminal 29.
+24Vdc seen at terminal 29 = AFD goes to Jog frequency.
0Vdc seen at terminal 29 = No jog for AFD.
