HC63N4D DC choke is not included with drive Requires inductance of approximately 3%, such as AC line reactor be installed. Electrical isolation Between power and control (inputs, outputs, power supplies) Acceleration and deceleration ramps Ramp profiles: Linear, can be adjusted separately from 0.01 to 9999 s S, U or customized Automatic adaptation of deceleration ramp time if braking capacities exceeded, possible inhibition of this adaptation (use of braking resistor) Braking to a standstill By DC injection: By a command on a programmable logic input Automatically as soon as the estimated output frequency drops to < 0.1 Hz, period adjustable from 0 to 60 s or continuous, current adjustable from 0 to 1.2 In (in open loopmode only). Main drive protection and protection features Thermal protection: Against overheating Of the power stage Protection against: Short-circuits between motor phases Input phase breaks Overcurrents between output phases and ground Overvoltages on the DC bus A break on the control circuit Exceeding the limit speed Line supply overvoltage and undervoltage Input phase loss, in three-phase Motor protection Thermal protection integrated in drive via continuous calculation of I2t taking speed into account: The motor thermal state is saved when the drive is powered down. Function can be modified via operator dialogue terminals, depending on the type of motor (force-cooled or self-cooled). Protection against motor phase breaks Protection with PTC probes Dielectric strength ATV61H ppp M3 ATV61H ppp M3X Between ground and power terminals: 2830 V c Between control and power terminals: 4230 V c ATV61 pppp N4 ATV61H ppp S6X Between ground and power terminals: 3535 V c Between control and power terminals: 5092 V c ATV61H ppp Y Between ground and power terminals: 3110 V c Between control and power terminals: 5345 V c Insulation resistance to ground > 1 M W (electrical isolation) 500 V c for 1 minute Frequency resolution Display units Hz 0.1 Analog inputs Hz 0.024/50 Hz (11 bits)
