Description
Application Scenarios:
It is 02:00 at a wastewater pumping station. A 1336 PLUS II drive on a raw-water pump has tripped, the SCADA screen shows only “Drive Fault”, and the on-call technician has a laptop in the van but no licensed configuration software, no correct cable, and no patience for a midnight software install. What he needs is the drive to tell him what happened, in words, on the spot.That is the job 1201-HAS2 was built for. On sites full of legacy Allen-Bradley drives — 1336, 1336 PLUS II, 1336 FORCE, 1336 IMPACT, 1336 REGEN — the HIM is the difference between a five-minute reset and an hour of guessing. The pain points it removes are consistent across water, cement, metals, mining, HVAC and general manufacturing:
- No dependence on a PC — parameter setting, monitoring, fault diagnosis and commissioning done at the drive door with a keypad.
- Faster fault resolution — the fault and warning queues are readable directly on the module, so “drive fault” becomes a specific, actionable code.
- Local control when the network is down — start, stop, jog, speed reference and direction from the module itself, independent of PLC or SCADA.
- Remote-mount flexibility — the HIM can be lifted out of its drive-mounted cradle and used remotely, which is how many panels give operators safe access without opening the enclosure.
- Keeping an installed base alive — 1201-HAS2 is discontinued, so a verified spare is what allows a healthy 1336 drive to stay in service instead of being written off as unsupportable.
The module divides into two logical sections, exactly as the 1336 FORCE documentation describes: a Display Panel for programming and viewing operating parameters, and a Control Panel (ESC / SEL / JOG) for commanding drive functions. That split is why operators with no programming background can still run the drive safely.
3. Parameter:

| Product Line | 1336 Adjustable (1336, 1336 PLUS, 1336 PLUS II, 1336 FORCE, 1336 IMPACT, 1336 REGEN — product families 1336F, 1336S) |
| Core Function | Programming the drive and viewing operating parameters; controlling drive functions (start, stop, jog, speed) from the front of the drive |
| Display | Integrated LCD screen showing parameters, status, operating values and fault codes |
| Input | Physical membrane keypad — Display Panel for parameter navigation, Control Panel with ESC / SEL / JOG for drive commands |
| Analog Control | Integrated analog potentiometer for local speed reference — speed can be trimmed by hand during commissioning |
| Power Supply | 5 V DC, approx. 160 mA, taken from the host drive — no separate power supply needed |
| Interface | Dedicated drive interface; connects directly to the 1336 drive and can be removed from its cradle for remote operation |

| Lifecycle Status | Discontinued / obsolete by the manufacturer — available as new surplus or refurbished through the obsolete-parts channel |
4. Technical Principles and Innovative Values:
Innovation Point 1 — Intelligence at the drive, not in the laptop: 1201-HAS2 puts the full parameter set of a 1336 drive behind a keypad and screen mounted on the drive itself. Commissioning, tuning and troubleshooting become local acts. In an industry where the most expensive resource during a fault is a qualified technician’s time, removing the boot-the-laptop / find-the-cable / match-the-firmware loop is a genuine productivity gain.Innovation Point 2 — Two-panel architecture that separates viewing from commanding: The Display Panel handles programming and monitoring; the Control Panel with ESC, SEL and JOG handles drive commands. This physical separation means an operator can run the process without ever entering a parameter edit mode — a simple, effective safeguard against unintended configuration changes during production.Innovation Point 3 — Fault and warning queues on the front panel: Rather than a single “fault” LED, the HIM exposes the drive’s fault and warning history. Post-trip analysis starts immediately at the machine, which shortens diagnosis from “call the drives specialist” to “read the code, clear the cause, restart”.Innovation Point 4 — Built-in analog pot for real-world commissioning: The integrated analog potentiometer lets a technician jog a conveyor, inch a pump or sweep a fan speed by hand while watching actual current and speed on the same screen. Mechanical alignment, belt tracking and rotation checks all get faster and safer.Innovation Point 5 — Powered from the drive, no additional infrastructure: Running on 5 V DC at roughly 160 mA drawn from the host drive, 1201-HAS2 adds no power supply, no wiring and no panel space beyond its own cutout. That is why it appears in the 1336 accessories catalogue as a drop-in option rather than a system project.Innovation Point 6 — Removable cradle design for remote operation: The HIM can be taken out of its drive-mounted cradle and operated remotely, supporting door-mounted or desk-mounted operator access. Rockwell’s documentation pairs this with a clear safety rule — a blank cover plate (option HAB) must be fitted when the HIM is absent — so the design protects people as well as equipment.Innovation Point 7 — One interface across an entire drive family: Because the 1336 family was designed with common control interface functions across the whole power range — from fractional kilowatt up to several hundred kilowatt — a technician who knows 1201-HAS2 can work on every 1336 drive in the plant. Training and maintenance commonality is the quiet, compounding benefit here.
