P46 Setting 2 - Program Keypad or Communication Module Control
This input mode activates the Start and Reverse functions from either the Program
Keypad Module (PKM), Remote Keypad Module, CopyCat Keypad Module or
plug in communication modules and deactivates the Start and Reverse inputs on
the control terminal block (TB3). Note: the frequency reference can be controlled
from the keypad modules or communication modules by setting
P59 - [Frequency
Select] to a setting of “1”. The frequency will then be controlled by the value
programmed into P58 - [Internal Frequency] .
Program Keypad Module control Figure 2.6
➊
When performing start and reverse operations from the Program Keypad Module, Remote Keypad
Module, CopyCat Keypad Module or plug-in communication modules, the Start and Reverse inputs
from the Control Terminal Block (TB3) are disabled.
P46 Setting 3 - Momentary Run Forward/Run Reverse Control
This input mode allows the drive to respond to either a momentary or maintained
Run Forward or Run Reverse input, but requires a stop input to TB3 terminals 7
and 8 to command the drive to stop. In addition, this is the only input mode that
uses “level triggered” control logic, therefore once the stop command is removed
or if power is lost and restored, the drive will immediately restart if a maintained
Run command is present.
Momentary Run Fwd/Run Rev control Figure 2.7
➊
A momentary or maintained input can be used. If using maintained inputs, please read the
Attention statement above.
➋
A normally closed maintained input is recommended. See Attention statement above.
ATTENTION: Hazard of injury exists due to unintended operation.
When P46 - [Input Mode] is set to 3, and the Run input is maintained,
the Run inputs do not need to be toggled after a Stop input for the
drive to run again. A Stop function is provided only when the Stop
input is active (open).
