Selection of the mode of stopping.
Ramp adjustment.
Control of an electro-mechanical brake.
• Following ramp (with prolongation depending on the inertia) :
b2 = 0, b7 = 0.
• Freewheel : b2 = 0, b7 = 1.
• With D.C. injection : b2 = 1, b7 = 0 :
- level adjustable via P8.
• Following ramp b2 = 1, b7 = 1.
• Time adjusted via P3.
• Via logic output A3 with b53 = 1 or via the assignable relay
with b50 = 1.
Adjustment of the switching frequency.
Vibration : prohibit critical frequencies.
Motor protection and torque limitation.
Slip compensation.
• Adjust b14.
• 3 skip frequencies programmed in P10 to P12.
• Skip band adjustable via P13 to P15.
• Adjustment of the maximum overload current via P4.
• Adjustment of the maximum continuous current via P5.
• Integration of I x t overload depends on P4 and P5.
• External limitation of the torque via terminal C4.
• Variable depending on the load via P7.
