25A-V4P8N104 — 525 Series AC Drive, 120V Single-Phase, 0.75 kW, EtherNet/IP

The 25A-V4P8N104 is a 0.75 kW / 1 HP variable frequency drive from the 525 series, configured for 100–120V AC single-phase input. Output current is 4.8A to a three-phase motor. Like the rest of the 525 platform, it ships with dual-port EtherNet/IP built in — no add-on communication card required — and carries Safe Torque Off inputs and a secondary option port as standard features regardless of power rating.

Single-phase 120V drives serve a specific market: equipment running from standard North American outlets, small machines without three-phase supply access, and laboratory or light industrial applications where the motor load is genuinely in the 0.5–1 HP range. Adding an EtherNet/IP drive at this power level — rather than a basic V/Hz-only drive — is relevant when the machine is part of a networked system and drive status, speed feedback, or remote control is useful to the operator or the control system.

Speed Control Without a Networked PLC

The 525 series has enough onboard I/O to run a complete standalone speed control application without any external controller. A few common configurations using only the drive's built-in terminals:

Potentiometer speed reference: wire a 1–10 kΩ pot between the drive's internal 10V reference and the 0–10V analog input. The pot wiper sets the speed reference from 0 to maximum frequency. A maintained contact start input and a normally closed stop input complete the basic control circuit.
Two-speed operation: configure two digital inputs as preset speed selections. Switch between them with a selector switch to toggle between a defined slow speed and a defined fast speed — no PLC, no analog signal required.
PLC analog control: connect a PLC analog output (0–10V or 4–20 mA, depending on the input configuration) to the drive's analog input. The PLC issues speed commands via the analog signal; the drive reports run status through the hardwired relay output.

The EtherNet/IP option layers on top of any of these — it doesn't replace the hardwired control capability, it extends it. A standalone potentiometer-controlled drive can still report its output frequency, current, and fault status to a SCADA system over EtherNet/IP while being controlled locally through wired inputs.

When the 525 Platform Is the Right Fit at This Power Level

Several drives in the 0.75 kW range are available at lower feature counts. The 525 series makes sense at 0.75 kW when any of the following apply:

The installation is part of a machine or system that uses EtherNet/IP for other components — drives, I/O, HMIs — and drive visibility on the network has operational value.
The safety architecture requires a rated STO function at this drive, not just a contactor upstream. The hardwired STO inputs on the 525 provide Category 3 / PLd without additional hardware.
Sensorless vector control is needed for better low-speed torque or tighter speed regulation than V/Hz provides — for example, a mixer handling product of varying viscosity where speed must be consistent regardless of load.
The application may grow, and the option port accommodates a future encoder feedback card or secondary communication card without replacing the drive.

FAQ

Q: Can this drive run from a 240V single-phase supply?

No. The 25A series input is rated for 100–120V single-phase. For 200–240V single-phase, the 25B-B (240V single-phase) variant is the correct choice.

Q: How is the IP address assigned for first-time network connection?

The drive defaults to BOOTP. Connect to a network with a BOOTP server to receive an IP address automatically, or use the HIM keypad to set a static IP address manually before connecting. Static addressing is recommended for production installations.

Q: Does the drive need to be derated for ambient temperatures above 40°C?

Yes. Output current derating begins at 40°C, approximately 1–2% per degree Celsius above 40°C up to the 50°C maximum. At 50°C ambient, the available output current is reduced by roughly 10–20% depending on the specific frame size. If the panel interior regularly exceeds 40°C, account for this derating when sizing the drive.

Q: Is a separate input EMC filter required for CE compliance?

The 525 series includes an internal EMC filter. For CE compliance in Category C2 environments (second environment, industrial), the internal filter typically meets requirements with motor cables under 10–15 m. For Category C1 (first environment, residential or light commercial), an additional external filter may be required. Verify against the specific installation's EMC requirements.

Q: What is the STO response time — how quickly does the drive stop producing torque after STO activation?

STO response time on the 525 series is less than 10 ms from input de-energization to gate pulse inhibit. This meets the requirements for STO in Category 3 / PLd safety architectures. Verify the actual response time against the safety function's required performance level in the machine's risk assessment documentation.
