    Failure of control board in VSD

    I haven't had experience with PDL drives but I have encountered capacitor failures on control cards from other drive systems. Check the ripple on the DC bus. Usually a 13 % ripple suggests a supply phase loss and could result in capacitor failures. Also, check the circuitry if there is a...

    Pump capacity

    We are currently planning to attach a supply hose to an existing pipeline through a three way valve (in combination with non-return valves to avoid cross-contamination). We purchased a solenoid metering pump with a capacity of 2 bars @ 32 l/h and connector size 12x9 to supply a 40% nitric acid...

    Drive in vector control mode

    It depends whether you want to run vector speed or vector torque control. 1 for the former and 2 for the latter. You can set the gains yourself in group 23 or you could do an autotune by entering 1 in parameter 2305. Make sure the motor load is connected for this autotune. For the ID run...
