Delta C2000 Plus, C2000-HS, C2000-R Manual

System Architecture Overview

Overview of Parallel Control

The parallel solution model is suitable for AC motor drives with the same power of 220kW and above (C2000 Plus, C2000-HS and C2000-R). It addresses the need for capacity expansion in high-power control by enabling internal communication between two AC motor drives (master/ slave) for parallel expansion control. This solution integrates optical fiber communication and system codes to ensure effective parallel control.

In parallel application, due to communication limits, the carrier wave can only reach up to 6 kHz, and the current specification should take 8% derating coefficient (multiplied by 0.92) into consideration when selecting AC motor drive models.

Delta's high-power frequency conversion solutions are divided into two categories:

NOTE:

• Ensure that the two parallel-connected drives are the same series models with the same power.
• The six-phase motor does not require the output reactors.

NOTE: *The rated current is based on the default load mode rated current of each model.

C2000 Plus
Table 1-3

NOTE:

1. *: The default setting is heavy duty mode.
2. The carrier frequency is default. Increasing the carrier frequency requires a reduction in current. Refer to Section Derating Curve for details inC2000 PlusUser Manual.
3. The AC motor drive should operate in derating current when its control method is set to FOC Sensorless, TQC+PG, TQC sensorless, PM+PG or PM sensorless. Refer to description of Pr.06-55 inC2000 Plus User Manual for more information.
4. The rated input current will be affected by not only power transformer and the connection of the reactors on the input side, but also fluctuates with the impedance of power side.
5. Model VFD4500C43x-xx, VFD5000C43x-xx and VFD5600C43x-xx do not have UL certification.
6. Rated output capacity is calculated by 460 V_AC, it is as a reference for the mains power drive capacity selection.

C2000-HS
Table 1-4

NOTE:

1. The carrier frequency is default. Increasing the carrier frequency requires a reduction in current. Refer to Section Derating Curve in C2000-HS User Manual.
2. Select the AC motor drive with capacity one grade larger for the impact load application.
3. The rated input current will be affected by not only Power Transformer and the connection of the reactors on input side, but also fluctuates with the impedance of power side.
4. For Frame D0 and above, if the last character of the model is A then it is under IP20 protection level, but the wiring terminal is under IP00 protection level.

Accessories Overview

CMC-FB01 -- Fiber Communication Card
When the AC motor drive is used in parallel control, the master and slave drive communicate with each other through optical fiber. This communication relies on the SPI interface between the MCU and the FPGA optical fiber card. The transmission and reception of signals are completed during each PWM cycle.

Figure 1-1

• In C2000 series, the optical fiber communication card is installed in Slot 2 by default. If you need to install the communication card in Slot 1, contact Delta for further information.
• Delta provides two length options for the required fiber optic communication cables.

Table 1-6

• In the diagram on the left:
  • The left upper corner and the right lower corner are the screw fixing holes.
  • The connector on the bottom of the board are fiber optical communication cables, the black one is RX, and the gray one is TX.

Reactor
During the parallel control, if there is no reactor installed on the output side, some of the current from the drive flows into the parallel drive and causes circulating current. Install an output reactor can prevent the above circulating current occurs. Refer to the user manual of each drive models in Delta Download Center for reactor selections.

Wiring

After removing the front cover, verify that the power and control terminals are clearly noted. Read the following precautions before wiring.

Turn off the AC motor drive power before doing any wiring. A charge with hazardous voltages may remain in the DC bus capacitors even after the power has been turned off for a short time. Measure the remaining voltage with a DC voltmeter on +1/DC+ and DC- before doing any wiring. For your safety, do not start wiring before the voltage drops to a safe level (less than 25 VDC). Installing wiring with a residual voltage may cause personal injury, sparks, and short circuit. Only qualified personnel familiar with AC motor drives are allowed to perform installation, wiring and commissioning. Make sure the power is turned off before wiring to prevent electric shock. Make sure that power is only applied to the R/L1, S/L2 and T/L3 terminals. Failure to comply may result in damage to the equipment. The voltage and current must be in the range indicated on the nameplate. Refer to the nameplate information in the User Manual of each models for details: C2000 Plus User Manual: https://downloadcenter.deltaww.com/downloadCenterCounter.aspx?DID=22212&DocPath=1&hl=en-US C2000-HS User Manual: https://downloadcenter.deltaww.com/downloadCenterCounter.aspx?DID=42836&DocPath=1&hl=en-US C2000-R User Manual: https://downloadcenter.deltaww.com/downloadCenterCounter.aspx?DID=44189&DocPath=1&hl=en-US All units must be grounded directly to a common ground terminal to prevent damage from a lightning strike or electric shock and reduce noise interference. Tighten the screws of the main circuit terminals to prevent sparks caused by screws loosened due to vibration.

For your safety, choose wires that comply with local regulations when wiring. Check the following items after finishing the wiring: Are all connections correct? Are there any loose wires? Are there any short circuits between the terminals or to ground?

Parallel Setup Steps

C2000 Series Settings
The following is the setting process and descriptions of C2000 series parallel connection, re-power the drive after completing the set up.

C2000 Series Tuning

• Control and communication parameters can be set on the master drive
• Motor and protection parameters must be identical on both the master and slave drives
• Currently, only speed mode (Pr.00-10=0) is supported

Master Drive Parameter Setting

1. Set Pr.00-02 = 10 (Parameter reset).
2. Set motor parameters in the Parameter Group 05.
3. Set Pr.00-62 = 1 (Master unit).
4. Check Pr.00-63 (Fiber communication card firmware version).
5. Set Pr.00-64 = 8 (Keypad setting: bit3 = 1, Parallel start).
6. Set Pr.00-11 according to the required mode (Currently supports IMVF and PM Sensorless).
7. Set Pr.00-17 carrier frequency (less than 6 kHz).
8. Set Pr.11-00 = 9.
9. Set Pr.10-53 = 1 (Only required for PM Sensorless).
10. Set parameters for Group 10 and Group 11.
11. Set Pr.00-04 to obtain the motor information: Pr.00-04=73 (output current), 74 (output power) and 75 (output torque).

Slave Side Parameter Setting:

1. Set Pr.00-02 = 10 (Reset parameters).
2. Set motor parameters in Parameter Group 05.
3. Set Pr.00-62 = 2 (Slave unit).
4. Check Pr.00-63 (Fiber communication card firmware version).
5. Set Pr.00-64 = 8 (bit3 = 1, Parallel start).
6. Set Pr.01-34 = 2 (minimum frequency)
7. Set Pr.00-11 according to the required mode (Currently supports IMVF and PM Sensorless).
8. Set Pr.00-17 to match the master drive's setting value.
9. Set Pr.00-20 = 9.
10. Set Pr.00-21 = 6.
11. Set Pr.11-00 = 9.
12. Set Pr.10-53 = 0.
13. Set parameters for Group 10 and Group 11.

Motor Parameter Autotuning

• In parallel model, the master drive must switch back to single unit mode before executing motor parameter autotuning, Pr.00-62 = 1 (master mode) changes to 0 (single unit mode). Be aware that the output side wiring of the Slave must be removed (as shown in the following figure), otherwise there is a risk of the Slave boosting the voltage.
  
• When driving a permanent magnet synchronous motor, execute the parameter autotuning according to Pr.05-00 settings.
• When driving an inductance motor and using speed tracking function by the motor vector flux (Pr.07-12 = 4), set the simple rolling auto-tuning for IM according to Pr.05-00 settings.
• After the autotuning is completed, re-connect the output wiring to the Slave and change the single unit mode back to master mode (Pr.00-62 = 1).
