Project settings: GA700 Platform 3 (firmware ≥ 1021)

Coordinates compressor start and stop sequences, solenoid valves, and the transition from startup speed control to pressure PID control. It converts an NTC sensor signal to temperature, controls a cooling fan, and generates alarms or faults for excessive pressure or temperature. Compressor PID parameters must be configured alongside the DWEZ program.

Drive compatibility: A1000, U1000, GA700

Project settings: A1000

Positions a load using encoder feedback and a PI position controller in closed loop vector control mode. Target positions are selected relative to a home switch; the drive generates the motion profile and holds the selected position while positioning remains enabled.

Project settings: GA700 Platform 3 (firmware ≥ 1021)

Detects an unbalanced rotating load by evaluating variations in torque reference or DC bus voltage. The washing-machine example evaluates the load during the steady drainage stage before high-speed spinning.

Drive compatibility: V1000, A1000, U1000, GA500, GA700

Project settings: GA700 Platform 3 (firmware ≥ 1021)

Synchronizes a follower drive with a master encoder or another drive in closed loop vector control mode. Supports speed following and angular synchronization, including multiple followers and an adjustable gear ratio. Parameters, digital inputs, or serial communication can select the operating mode and adjust the ratio.

Drive compatibility: A1000, U1000, GA700

Project settings: GA700 Platform 3 (firmware ≥ 1021)

Coordinates up to three pumps using pressure or flow feedback without an additional PLC. Duplex and triplex programs alternate pump starts according to accumulated operating time; lag variants add pumps when the lead pump reaches its control limit. The DWEZ programs manage pump start and stop signals, while the drive PID settings provide pressure regulation.

Drive compatibility: GA700

Project settings: GA700 Platform 4 (firmware ≥ 1028)

Controls a mechanical brake for applications using open loop vector control. Brake release and holding are coordinated with drive frequency, current, and adjustable delays; separate programs are provided for A1000, GA700, U1000, and V1000.

Drive compatibility: V1000, A1000, U1000, GA500, GA700

Project settings: V1000, A1000, U1000, GA700 Platform 3 (firmware ≥ 1021)

Monitors drive output current and increases conveyor speed as the load rises. The supplied examples provide linear and quadratic speed-increase variants.

Drive compatibility: V1000, A1000, U1000, GA500, GA700

Project settings: GA700 Platform 3 (firmware ≥ 1021)

Demonstrates a timed direction sequence: forward operation for nine seconds, a ten-second pause, and reverse operation for nine seconds.

Drive compatibility: V1000, A1000, U1000, GA500, GA700

Project settings: GA700 Platform 3 (firmware ≥ 1021)

Limits output current indirectly through the torque limit using a configurable four-point curve with linear interpolation between points. The reference points can be changed during operation, and the approach can be adapted to output-power limitation.

Drive compatibility: A1000, U1000, GA500, GA700

Project settings: GA700 Platform 4 (firmware ≥ 1028)

Decelerates a spindle and positions its rotor at a predefined angle using encoder feedback in closed loop vector mode. A digital input activates orientation and holding; releasing it allows normal operation to resume without cycling the run command.

Drive compatibility: A1000, GA700

Project settings: GA700 Platform 3 (firmware ≥ 1021)

Steps through four frequency references, each with an adjustable dwell time after the reference is reached. The sequence can repeat continuously or finish at a fifth continuous-run reference, and a digital input can restart it.

Drive compatibility: V1000, A1000, U1000, GA500, GA700

Project settings: GA700 Platform 3 (firmware ≥ 1021)

Detects a clogged filter at a fan inlet or outlet by monitoring the torque reference. The function depends on the torque signal and is unsuitable for V/f control.

Drive compatibility: A1000, U1000, GA500, GA700

Project settings: GA700 Platform 3 (firmware ≥ 1021)

Uses one GA700 and three switching relays to start two motors sequentially, transferring the first motor to the mains before accelerating the second. It supports coast-to-stop and ramp-to-stop sequences; the latter reconnects the first motor through speed search for controlled deceleration. Relay sequencing, frequency monitoring, and boot protection coordinate the transfers. The ramp-to-stop sequence is intended for high-inertia loads that keep rotating during the changeover delay.

Measures the duty cycle of a PWM signal connected to a digital input and converts it to a value such as a frequency reference. The measurement adapts dynamically to changes in PWM frequency.

Project settings: V1000

Demonstrates Remote I/O communication from a GA700 master to a V1000 slave over MEMOBUS. The slave mirrors the master frequency reference, forward and reverse run commands, external fault, and fault reset.
