Page 46: Single Phase Input Utility Wiring And Operation
Chapter 2: Installation and Wiring Single Phase Input Utility Wiring and Operation Ironhorse ACN is a three-phase standard variable frequency drive(VFD). When applying single-phase power to a three-phase VFD, there are several constraints that need to be considered. Standard Pulse-Width-Modulated (PWM) VFDs use a 6-pulse diode rectifier.
Page 47: Power (Hp), Input Current And Output Current
Chapter 2: Installation and Wiring Power (HP), Input Current and Output Current When using a three-phase VFD with single-phase input, derating the drive’s output current and horsepower will be necessary because of the increase in DC bus ripple voltage and current. In addition, the input current through the remaining two phases on the diode bridge converter will approximately double, creating another derating consideration for the VFD.
Page 48: Control Terminal Wiring

Page 165: Setting Acceleration And Deceleration Times
Chapter 4: AC Drive Parameters Setting Acceleration and Deceleration Times Acc/Dec Time Based on Maximum Frequency Acc/Dec time values can be set based on maximum frequency, not on drive operation frequency. To set Acc/Dec time values based on maximum frequency, set bA.8 (Acc/Dec reference), = 0 (Max Freq). Acceleration time set at the ACC (Acceleration time) code in the Operation group (dr.3 in an LCD keypad) refers to the time required for the drive to reach the maximum frequency from a stopped (0Hz) state.
Page 166: Acc/Dec Time Based On Operation Frequency
Chapter 4: AC Drive Parameters Acc/Dec Time Based on Operation Frequency Acc/Dec times can be set based on the time required to reach the next step frequency from the existing operation frequency.

Page 175: Output Voltage Setting
Chapter 4: AC Drive Parameters Auto Torque Boost–2 In V/F operation, this adjusts the output voltage if operation is unavailable due to a low output voltage. It is used when operation is unavailable, due to a lack of starting torque, by providing a voltage boost to the output voltage via the torque current.
Page 176: Start After Dc Braking
Chapter 4: AC Drive Parameters Start After DC Braking This start mode supplies a DC voltage for a set amount of time to provide DC braking before the drive starts to accelerate a motor. If the motor continues to rotate due to its inertia, DC braking will stop the motor, allowing the motor to accelerate from a stopped condition.
Page 177: Stop After Dc Braking

Page 293: Rs-232C To Rs-485 Conversion
Chapter 5: Serial Communications RS-232C to RS-485 Conversion In an RS-485 communication system, the PLC or computer is the master device and the drive is the slave device. When using a computer as the master, the RS-232 converter must be integrated with the computer, so that it can communicate with the drive through the RS-232/RS-485 converter.
Page 294 Chapter 5: Serial Communications RS-232C to RS-485 Conversion Many AutomationDirect PLCs have only RS-232C communication ports, and require an FA-ISOCON (RS-232C to RS-422/485 network adapter) in order to make an RS-485 connection. NOTE: If an FA-ISOCON module is used, set the module dipswitches as required. Refer to the FA-ISOCON manual for more detailed information.
Page 295 Chapter 5: Serial Communications Communication Cable Connection Make sure that the drive is turned off completely, and then connect the RS-485 communication cable to the S+/S-/ SG terminals of the terminal block. The maximum number of drives you can connect is 16. For communication wiring, use shielded twisted pair (STP) cables.

Page 343 Appendix A: Accessories 4) The subpanel or metal plate used to support the EMI filter and ACN drive should be well grounded (minimal resistance to ground is typically less then 1Ω). 5) To insure that the EMI filter and ACN drive are adequately grounded, insure that both are securely attached to the subpanel or plate Choose suitable motor cable and precautions Proper installation and the the choice of good motor cable will positively affect the performance of the filter.
Page 344: Recommended Motor Cable Length
Appendix A: Accessories Reflective Wave Phenomenon The drive section of a PWM drive like the ACN does not produce sinusoidal output voltage wave forms. Rather, the output voltage produced is a continuous train of width modulated pulses, sent to the motor terminals via the motor cable.
Page 345: Line Reactors / Voltage Time Filters
Appendix A: Accessories Line Reactors / Voltage Time Filters Line Reactor Installing an AC reactor on the input side of an AC motor drive can increase line impedance, improve the power factor, reduce input current, increase system capacity, and reduce interference generated from the motor drive. It also reduces momentary voltage surges or abnormal current spikes from the mains power, further protecting the drive.
Page 346: Dc Reactor
Appendix A: Accessories DC Reactor A DC reactor can also increase line impedance, improve the power factor, reduce input current, increase system power, and reduce interference generated from the motor drive. A DC reactor stabilizes the DC bus voltage. Compared with an AC input reactor, a DC reactor is in smaller size, lower price, and lower voltage drop (lower power dissipation).

Page 348 Appendix A: Accessories Output Side of AC Drive When installed on the output side of the ACN drive, line (load) reactors help to protect the ACN drive from short circuits at the load. Voltage and current waveforms from the ACN drive are enhanced, reducing motor overheating and noise emissions.
Page 349: Multiple Motors
Appendix A: Accessories Multiple Motors A single output (load) reactor can be used with multiple motors on the same ACN drive, but only if the motors operate simultaneously. Size the reactor based upon the total horsepower of all the motors, and select a reactor with a current rating greater than the sum of the motor full-load currents.
Page 350: Single-Phase Applications
Appendix A: Accessories Single-Phase Applications Some three-phase line reactors are listed for use with single-phase input power. Follow the connection diagram shown below. Make sure that terminals B1 and B2, if present, are properly insulated before any connections are made. If a 3-phase reactor is used on the line side of a single-phase input drive application, ensure that the actual single-phase current does not exceed the Line Reactor's current rating (example: a 3-phase, 5hp line reactor and 3-phase 5hp drive will not handle enough current to power a 5hp motor on a single-phase supply - both the drive and the line reactor will have to be doubled).
Page 351: Dynamic Braking
Appendix A: Accessories Dynamic Braking Dynamic braking resistors dissipate the regeneration energy of AC motors when they are being controlled to a stop faster than a coasting stop. GS series brake resistors can be used with ACN drives. All drives have the braking function built-in and do not require a separate dynamic braking unit.

AutomationDirect for the power calculation. 4) Refer to the ADC Dynamic Braking unit User Manual for more detail on braking resistors (https://cdn.automationdirect.com/static/manuals/gs3dbm/gs-db_ump.pdf) 5) The selection tables are for 5% duty cycle. If the AC motor drive requires frequent braking, increase the Watts by two to three times.

It sets up the data format of the drive status sent from the drive to the Client (Originator) during the I/O communication module of the CIP (Common Industrial Protocol).
Page 431: Cip Output Instance
Appendix C: Ethernet Module ACN-ETH CIP Output Instance(CM.49) This parameter is displayed only when protocol is set to EtherNet/IP. It sets up the data format of the drive command sent from the Client (Originator) to control the drive during the I/O communication module of the CIP (Common Industrial Protocol).
Page 432: Parameter Status
Appendix C: Ethernet Module ACN-ETH Parameter Status (CM.31~CM.38) These parameters can be utilized by Modbus TCP or EtherNet/IP. Enter the hex address of the desired drive parameter or common address. This is sent for the reference data of the Client (Originator) at the same number as that of the set parameters in the CM.31~CM.38.
