M1.7-1 Brake pot minimum voltage level “BrkMin”
This parameter is active if “M2-9 Analog Input 2 configuration “AI2Cfg”” is set to 0. In this way, the AI2 is
configured to work as a brake pot.
• If the input is configured as “Brake pot” (“M2-9 Analog Input 2 configuration “AI2Cfg”” set to 0), this sets
the voltage on the Footbrake input that will correspond to begin footbrake operation. Notice that as soon
footbrake is pressed and footbrake input voltage greater than “BrkMin”, a foot brake operation is started.
In “Torque mode”, the brake torque applied will depend on Footbrake value;
In “Speed Mode”, the footbrake deceleration ramp will depend on Footbrake value.
For tuning this parameter refer to “APPENDIX C – Analogue Input tuning”.
M1.7-2 Brake pot maximum voltage level “BrkMax”
This parameter is active if “M2-9 Analog Input 2 configuration “AI2Cfg”” is set to 0. In this way, the AI2 is
configured to work as a brake pot.
• If the input is configured as “Brake pot” (“M2-9 Analog Input 2 configuration “AI2Cfg”” set to 0):
In “Torque mode”, this sets the voltage on the Footbrake input that will correspond to the braking
torque as set by the parameter “M1.1-9 Foot brake torque “FBrake””.
The brake torque is changed proportionally to “Brake Pot Value” (see brake pot value in test menu
“M11-11 "BrakePot" [%]” and “M11-12 "BrakePot" [V]”) from “M1.1-3 Neutral brake torque
“NBrake”” (when “Brake Pot” = 0%) to “M1.1-9 Foot brake torque “FBrake”” (when “Brake Pot” =
100%).
In “Speed Mode”, this sets the voltage on the Footbrake input that will correspond to the braking
ramp for speed as set by the parameter “M1.1-10 Foot brake ramp time “FBrkRamp””.
The ramp time for braking is changed proportionally to “Brake Pot Value” (see brake pot value in test
menu M11-11 "BrakePot" [%], M11-12 "BrakePot" [V]) from “M1.1-4 Neutral brake ramp time
“NBrkRamp””(when “Brake Pot” =0%) to “M1.1-10 Foot brake ramp time “FBrkRamp”” (when “Brake
Pot” =100%).
For tuning this parameter refer to “APPENDIX C – Analogue Input tuning”.
M1.7-3 Analogue Input 2 minimum voltage level “AI2 min”
This adjustment is active if “M2-9 Analog Input 2 configuration “AI2Cfg”” is set to greater than 0. In this way,
the AI2 is configured to work as an analogue torque or speed limit.
• If the input is configured as “Analogue torque limit” (“M2-9 Analog Input 2 configuration “AI2Cfg”” set
to 1), this sets the voltage on the analogue input 2 that will correspond to 0% drive torque limit.
• If the input is configured as “Analogue speed limit” (“M2-9 Analog Input 2 configuration “AI2Cfg”” set
to 2 or 3), this sets the voltage on the analogue input 2 that will correspond to 0 rpm speed limit.
For tuning this parameter refer to “APPENDIX C – Analogue Input tuning”.
