Fault 17: Motor Speed Stall – Cutting Unit 1
InfoCenter Display:
Fault Description
This fault is reported when cutting unit 1 was at zero RPM for more than 3 seconds. Insufficient torque exists
to rotate the reel motor.
Note:
The Greensmaster TriFlex 3320 and 3420 are designed to cut short grass on golf-course greens and
maintained turf on fairways. When using a TriFlex to cut longer grass on a fairway or in the rough, the cutting
unit motors may overheat simply because they are being overworked. Before trying to troubleshoot this fault,
interview the operator about the mowing conditions when the fault occurred. The source of the fault may be as
simple as the machine being used in a manner outside its designed purpose.
Note:
If your machine reports a Fault 13: High Temperature Warning – Reel Motor 1 and a fault 17,
troubleshoot the fault 13 first. A side effect of a fault 13 is reduced reel speed, which causes an increased
chance of a fault 17, Motor Speed Stall – Reel Motor 1.
Circuit Description
All three cutting reel motors and the starter/generator are linked on the 48 V CAN bus circuit.
