TL-A2540P-BJ34AA New Factory Sealed TLA2540PBJ34AA Servo Motor
PRODUCT DETAILS
TL-A2540P-BJ34AA — TL-Series Rotary Servo Motor, NEMA 34, 230V AC, 5000 RPM, with Brake
The TL-A2540P-BJ34AA is a NEMA 34 (90 mm) frame rotary servo motor from the TL series, rated for 230V AC operation at up to 5000 RPM. It carries a multi-turn absolute encoder with 17-bit (131,072 counts per revolution) resolution and battery-backed position retention, an IP65-rated housing with shaft key (no shaft seal), and an integrated 24V DC holding brake — covering general-purpose motion axes that need absolute position memory through a power cycle without requiring a homing sequence on every startup.

NEMA 34 With Absolute Feedback — What That Combination Solves
Absolute multi-turn feedback eliminates the homing routine that incremental-encoder motors require after every power cycle — the controller knows the axis's exact position the instant power is restored, since the encoder's battery backup retains position data through the outage. For machines where a homing move on every startup costs cycle time, creates a collision risk in a crowded mechanical envelope, or simply isn't acceptable for an operator-facing restart sequence, absolute feedback removes that step entirely.
The 24V DC holding brake is the companion feature that makes this practical on vertical or gravity-loaded axes: when the drive de-energizes, the brake engages mechanically to hold position, preventing the axis from drifting or falling before the controller re-establishes control. Combined with absolute feedback, the axis can be de-energized and re-energized without losing track of where it physically is or risking unintended motion in the interim.
FAQ
Q: Does this motor require a battery replacement to maintain absolute position memory?
Yes, on a periodic basis. The encoder's battery backup has a defined service life — replace it on the recommended interval to avoid losing absolute position reference, which would otherwise require a re-homing sequence.
Q: Can this motor be run without the holding brake engaged during normal operation?
Yes. The brake engages only when commanded — typically on drive disable or power loss — and stays released during normal powered operation, allowing free rotation under the drive's active control.
Q: Is the IP65 rating sufficient for wash-down environments?
IP65 covers dust ingress and water jets from any direction, but this motor specifically ships without a shaft seal — verify whether the application's wash-down exposure at the shaft area requires a sealed-shaft variant instead.
Q: Which Kinetix drive families is this motor compatible with?
TL-series motors are designed to pair with compatible Kinetix servo drive platforms supporting the appropriate feedback and cable interface — verify the specific drive model's motor compatibility list and required cable assemblies before specifying a drive-motor pairing.
