Page 15: Commissioning
5 Commissioning Commissioning Enable open, command value zero Switch on mains supply The motor must be at a torque-free standstill. Close the drive enable switch The LED ‘enable’ must light. Turn the command value potentiometer slowly up. The motor must accelerate according to the command value voltage. (If the motor immediately accelerates to full speed or if full voltage is immediately applying, the actual value connection across terminal 6-7 must be swapped). - Page 16 Classic C1 230/180 -4 (f) Amplification current controller If the armature circuit inductivity is high, all contacts of the switch S1 are in ‘OFF’ position. If the inductivity is low, all contacts are in ‘ON’ position. The adjusted values can be exactly measured by displaying the motor current on an oscilloscope.
