FAQ 

1.What are the overall length, width and depth, as well as the total weight of the VFD750CP43B-21?

The

• IP20 D frame wall-mounted sealed type,
• Overall machine dimensions (width 360mm × height 690mm × depth 280mm)
• Net weight of the entire machine: 38.4kg

2.What is the maximum number of pumps that can be linked with one VFD750CP43B-21 inverter?

Supported. The

• Scheduled rotation mode (all pumps operate in alternate variable frequency): Up to 8 pumps are supported. To achieve 8-pump output logic, a multi-pump relay expansion card must be selected.
• Quantitative addition and subtraction pump mode (variable frequency + constant frequency mixed use): Up to 4 pumps are supported. 1 variable-frequency pump + up to 3 constant-frequency pumps. This is the most commonly used mode in constant pressure water supply projects.

3.What are the maximum output frequency and the low-frequency starting torque values for the VFD750CP43B-21V/F in the SVC mode?

The

• In the V/F (scalar) mode, the maximum output frequency is 600Hz.
• In the SVC (sensorless vector) mode, the maximum output frequency is 400Hz.
• In the SVC mode, the low-frequency starting torque at 0.5Hz: ≥ 160% of the motor’s rated torque.

4.How many steps are there in the built-in PLC program of VFD750CP43B-21?

The

• PLC program capacity: 10,000 steps (10K Steps)
• Equipped with an RTC (Real-Time Clock) perpetual calendar real-time clock, it supports timing control, time division start/stop, and multi-pump linkage logic programming.
• Using software to write ladder logic, local logic control of the pump room can be achieved without the need for an external independent PLC.
