• Motor power control in trapeze mode ("6 steps").
• A speed control
• Torque limiting control
• Management of the four inputs and three outputs that control the motor:
o
Two 10-bit or PWM analogue control inputs
Speed set-point
Torque limiting
o
Two switching inputs
On/off
Direction of rotation
o
One encoder output
12 points per revolution for 80140 and 80180 motors
24 points per revolution for 80280 motors
o
One 'torque limit reached' switching output
o
One actual direction of rotation switching output
