Torque/Current Limitation Fault

What does SSF mean?

A torque/current limitation detected fault. This indicates that the drive's output torque or current has hit its predefined limit, typically due to an overload condition or an attempt to accelerate too quickly. While a protection feature, persistent limitation can indicate an undersized system or mechanical issue.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Increase acceleration/deceleration ramp times to reduce peak current demands.

2. 4

   Verify that the motor and drive are appropriately sized for the application's demands.
