The oscilloscope function is extremely useful when making adjustments. Thisfunctionissuitableforapplicationswherethedrivesaredifficulttoaccess,forexample on moving parts or in material handling systems. Values higher than this will cause loss of torque. These two keys can be made accessible on the front panel by removing the cover 4 from the door. These maximum lengths are given as examples only, as they vary depending on the stray capacitance of the motors and the cables used. Automatic adaptation must be cancelled if the machine has position control with stopping on a ramp and a braking resistor installed.
Enabled by means of 1, 2, 3 or 4 logic inputs. Themotorrestartsautomaticallyontherampwhenthereference reappears or if the run command is interrupted and then re-established. This function is suitable for lightweight machines, bulk product conveyors with an unbalanced motor, fans and centrifugal pumps. . Limit switch management bThis function is used to manage the operation of one or two limit switches with 1 or 2 operatingdirections. The shielding must be clamped tightly enough to the metal sheet to ensure good contact. The voltage is automatically reduced to minimum according to the necessary torque.
To ensure proper air circulation in the drive: Install ventilation grills bEnsurethatthereissufficientventilation. The contactor controls and manages any safety features and isolates the motor on stopping. The reference can be switched with the motor running. It is suitable for machines for which the motor speed loss is negligible during the loss of line supply such as machines with high inertia, fans and pumps driven by a residualflow,etc. It is enabled by 1 logic input and pulses given by the operating direction command. All faults are reset on a change of state of the logic input.
Freewheel stop bThis stops the motor by resistive torque if the motor power supply is cut. See the product references on page 40. Note: All terminals are located at the bottom of the drive. It is possible to prohibit prolonged operation of the motor on 1 or 2 frequency bands 1Hz ,aroundanadjustablefrequencyonthespeedrange. The resistors are designed to be mounted on the outside of the enclosure, but should not inhibit natural cooling.

It is suitable for pumping and ventilation applications. The nominal motor current should not exceed this value. Cover for optional access to the motor local control keys. Acceleration time: For hoisting applications it is advisable to set the acceleration -ramps to more than 0.

Brake engage frequency: Set to twice the nominal slip, then adjust according to -the result. The function can be used to adapt the motor parameters. Theres no need to open the enclosure! The switching frequency is modulated randomly in order to avoid resonance. Choose between 2, 4, 8 or 16 preset speeds.

Link 3 on the drive is then via the filter output cable. SoMove Mobile software for mobile phones 1 SoMoveMobilesoftwarecanbeusedtoeditdriveconfigurationsonamobilephone. They act as a support for the drives and are attached to them via tapped holes. This function limits the torque and the temperature rise of the motor. Comprehensive product offeringThe Altivar 312 range of variable speed drives covers motor power ratings from 0. The preset speeds are adjustable in increments of 0. Values higher than this will cause loss of torque.

The switching frequency can be adjusted during operation to reduce the noise generated by the motor. It is automatically disabled if the brakesequenceisconfigured. Switching must take place with the drive stopped and locked, using an appropriate sequence at the drive output. Speed detection can take up to 1 s depending on the initial deviation. This mode is used to display the monitoring parameters when the drive is running. S ramps v For applications such as material handling, packaging and passenger transport, the use of S ramps takes up mechanical backlash, eliminates jolts, and limits non-following of speed during rapid transient operation of high-inertia machines.
