Yaskawa Error Code A910 Link Hot! ❲EXCLUSIVE❳

A.910

The Yaskawa error code refers to an Overload Warning . This warning is a proactive alert that triggers before a full overload alarm (like A.710 or A.720) occurs, giving you a chance to intervene before the drive shuts down entirely.

Meaning:

Output Phase Loss (One or more output phases (U, V, W) to the motor are open/missing.) yaskawa error code a910 link

Parameter Settings

: If the Overload Warning Level (Pn52B) is set too low for the specific application, the alarm will trigger prematurely. Power cycle the drive – transient faults may clear

  1. Power cycle the drive – transient faults may clear.
  2. Check wiring – ensure twisted-pair shielded cable is used, shield grounded only at one end.
  3. Verify termination resistors – set correctly for the network.
  4. Test with a local keypad (directly mounted on drive) – if A910 clears, the link/cable/remote device is the problem.
  5. Reduce electrical noise – separate comm lines from power cables, use ferrite cores.
  6. Check settings – o1-05 (LCD contrast not related), but focus on F6-xx (for digital operator), H5-xx (for serial comm). Ensure parity, stop bits, baud rate match all devices.
  7. Replace cable – if damaged.
