Kudamm corporation manufactures variable frequency drives and plc of abb in different versions for requirements of application. The comp-ac range covers 0.12-37 kw and comprises acs 100, acs 140 and acs 400 product types. The ac drives are available with a selection of pre-set macros for fast commissioning, automatically configured macro-specific parameters and factory application macro intended for applications where drive is used without control panel. These instruments are applicable hvac, pid, pump and fan control and the model come in 1-phase/3-phase mains connection. The variable frequency ac drives & plc have dtc [direct torque control] which is ultimate in ac motor control performance, acs 600 for precise speed and torque control of standard squirrel cage motors ensuring overall effectiveness of drive limited by performance of motor not the frequency converter. These variable ac drives & plc ensure 200% of nominal motor starting torque and provide salient features such as accurate open long torque control; less than 5 ms torque step rise time; 0.1% to 0.5% of nominal speed control inaccuracy; factory setting for industrial applications; hand/auto control for local and remote operation; pid control for closed loop processes and user macro 1 and 2 for users own parameter settings.
