SPEED CONTROL PROGRAMMING OPTIONS
The following is a list of the speed control parameters that can be adjusted using a Curtis hand held programmers:
M1 MAX SPEED – Transport/Burnish speed maximum limit (% of full throttle)
M2 MAX SPEED – Burnishing speed factory default is 80%
M1 MIN SPEED – Transport/Burnish speed maximum limit with the speed limit pot in minimum position (% of full throttle limited by speed limit pot)
M2 MIN SPEED – Burnishing speed factory default is 30%
M1 REVERSE MAX SPEED – Reverse Transport/Burnish speed maximum limit (% of full throttle)
M2 REVERSE MAX SPEED – Default is 70%
REVERSE MIN SPEED – Transport/Burnish speed maximum limit with the speed limit pot in minimum position (% of full throttle limited by speed limit pot)
