1.
Plug in the keypad
2.
Ensure that controller inhibit is active after mains connection
Terminal X3/28 = LOW
3.
Switch on the mains
4.
After approx. 3 s the keypad is in the operating level and displays
the output frequency (C0050) and the device utilisation (C0056)
5.
For quick commissioning you select the "Quick start" menu
The submenu "V/f quick" contains the codes which
you require for commissioning a standard application.
The digital inputs are configured in the Lenze setting:
X3/E1, X3/E2: activation of fixed setpoints (JOG)
X3/E3: activation of DC injection brake (DCB)
X3/E4: CW rotation/CCW rotation
