FANUC Alarm SVGN-169 — PushDepth…[mm]clampd, speed affected
Manufacturer wording — PushDepth%s[mm]clampd, speed affected
The manual prints placeholders; your controller fills them in with the real group, axis or number.
FANUC SVGN-169 (“PushDepth…[mm]clampd, speed affected”): The minimum push depth (internally calculated distance) required to decelerate from the contact speed exceeds the maximum possible pushing depth: part thickness + close stroke limit. First check: Decrease $sggun#.$setup.$push_margin, or increase the close stroke limit.

Description
The minimum push depth (internally calculated distance) required to decelerate from the contact speed exceeds the maximum possible pushing depth: part thickness + close stroke limit. The value of the minimum pushing depth (specified in the alarm message) was clamped to the maximum possible pushing depth.
Remedy
Decrease $sggun#.$setup.$push_margin, or increase the close stroke limit. Although this alarm has a warn severity, this condition should be corrected since the minimum push depth has been clamped to a value that is small enough to affect contact speed and/or contact speed persistence. Note 1: SVGN-169, basically indicates that the close limit value is abnormal, since minimum push depth is typically less than 5mm. Note 2: part thickness is automatically added to the pushing depth value during tryout mode to compensate for the missing part.
