Lenze EMZ9371BB Keypad for 9300 Drive Controllers
A detachable operating unit for code access, diagnostics and controlled parameter-set handling on compatible Lenze 9300 equipment.
Key Information
EMZ9371BB is the Lenze keypad used with compatible 9300 drive controllers and Drive PLC hardware. It provides local code access, plain-text operating information and a portable memory for a stored 9300 parameter set.
Parameter transfer is not a complete drop-in replacement procedure. Controller-specific codes remain outside the copied data and must be checked separately before the receiving drive is enabled.
Functions
- Reads and writes supported drive codes from the local operating interface.
- Displays operating values, status information and diagnostic messages in plain text.
- Stores one parameter set non-volatilely for transfer between compatible 9300 controllers.
- Provides controller inhibit and release functions during supervised service work.
Specifications
| Manufacturer | Lenze |
|---|---|
| Model | EMZ9371BB |
| Product Class | Detachable keypad / operating unit |
| Compatible Platform | Lenze 9300 drive-controller family |
| Primary Uses | Local operation, diagnostics and parameter handling |
| Stored Data Role | One non-volatile 9300 parameter set |
| Important Limitation | Controller-specific codes are not all copied |
| Selection Check | Keypad software state and host-controller compatibility |
Installation
- Confirm the host controller type and keypad software state before fitting or transferring data.
- Back up the existing controller parameters and record communication addresses, baud rate and enable settings independently.
- After a transfer, verify the controller-specific codes, fieldbus node settings and application limits before release.
- Scroll through user-defined codes after a PLC project download so missing custom units can be identified before operation.
Lifecycle
- Store the keypad in a dry, protected location and keep it linked to the machine parameter archive.
- Record which controller and software version produced each saved data set.
- Retain a separate commissioning sheet for values that the keypad transfer does not carry.
FAQ
Can EMZ9371BB copy every setting to a replacement 9300 controller?
No. Address, baud-rate, enable and several controller-specific codes require a separate post-transfer check.
What should be recorded before using EMZ9371BB for parameter transfer?
Capture the source controller identity, software state, fieldbus address, communication rate, enable logic and application limits.
Can an EMZ9371BB data set be loaded into any 9300 unit?
Only use it with a compatible controller type and application. Hardware, software and option-board differences must be resolved first.
Why might communication fail after an EMZ9371BB transfer?
The communication address is not automatically carried in the copied parameter set, so the receiving controller may retain a different node value.
What is the safest acceptance check after fitting EMZ9371BB?
Review the fault history, verify all safety-related enable paths and test motion at controlled speed before production release.
What information is needed to quote EMZ9371BB?
Provide the keypad label, host-controller model, installed software state and whether the requirement is operation, backup or replacement.
