If the Access Level Selection is set to Advanced, all parameters should be adjustable unless: 1. The Drive parameters are password protected (A1-04) which will prevent access to A1-00 through A1-03 and all A2 parameters.
Page 104: B1 Sequence
A1-04 Password Entry Setting Range: 0 to 9999 Factory Default: 0 If parameters A1-01 through A1-03 and all of the A2 parameters are locked (unchangeable) they can be unlocked by entering the correct password number into A1-04. Once the correct password number is entered and the specified parameters are unlocked, a 2-Wire or 3-Wire initialization will reset the password to 0000.

Page 106 When the output frequency has dropped below the DC Injection Start Frequency in b2-01 (Default = 0.5HZ) DC current will be injected in the motor at a level determined by b2-02 (50% Default). The DC Injection condition will occur for the time specified by b2-04 (0.0 Default), to establish the end point of the ramp.
Page 107 2:DCInj to Stop: When the Run command is removed, the Drive will Baseblock (turn off its output) for the Minimum Base- block Time (L2-03). Once the Minimum Baseblock Time has expired, the Drive will inject DC current into the motor wind- ings to lock the motor shaft.
Page 108 b1-04 Reverse Operation Setting Description Reverse Enabled Reverse Disabled (factory default) Exchange Phase ExchgPhs, Rev Dsbl For some applications reverse motor rotation is not applicable and may even cause problems (e.g., air handling units, pumps, etc.). Setting parameter b1-04 to 1 or 3 will cause the Drive to ignore any inputs for reverse operation. Setting parameter b1-04 to either 2 or 3 will change the motor shaft rotation when a Forward Run command is given by exchanging the order of the output phasing.
Page 109: B2 Dc Braking
b1-08 Run Command Selection During Programming Setting Description Disabled Enabled (factory default) As a convenience to the user, the Drive will respond to a Run input even when the digital operator is being used to adjust parameters. If it is necessary that external Run commands not be recognized while the Drive is being programmed, set b1-08= “0: Disabled”.
Page 110 b2-02 DC Injection Braking Current Setting Range: 0 to 100% Factory Default: 50% The level of DC Injection Braking Current affects the strength of the magnetic field attempting to lock the motor shaft. Increasing the level of current will increase the amount of heat generated by the motor windings and should only be increased to the level necessary to hold the motor shaft.
Page 111: B3 Speed Search
b3 Speed Search The Speed Search function allows the Drive to determine the speed of a motor shaft that is being driven by rotational inertia. Speed Search will allow the Drive to determine the speed of the already rotating motor and begin to ramp the motor to a set speed without first having to bring it to a complete stop.

Page 121 The analog feedback to the Drive for the PI control is via the Drive A2 terminal. The Drive must be programmed (H3-09= “B: PI Feedback”) to use terminal A2 as feedback for the PI functionality of the Drive. The PI setpoint can be configured to come from one of many different inputs or parameters. The table below describes the options for originating the PI setpoint.
Page 122 The Integral factor of PI functionality is a time-based gain that can be used to eliminate the error (difference between the setpoint and feedback at steady state). The smaller the Integral Time set into b5-03, the more aggressive the Integral factor will be.

Page 125 b5-17 PI Accel/Decel Time Setting Range: 0.0 to 25.5 Seconds Factory Default: 0.0 Seconds This is a soft start function that is applied to the PI setpoint analog input. Instead of having nearly instantaneous changes in signal levels, there is a programmed ramp applied to level changes. When changing setpoints the error can be limited by gradually ramping the setpoint through the use of parameter b5-17.
Page 126 If the monitors seem more natural in terms of percentage, set b5-20= 1. If the monitors are easier to work with when displaying the equivalent synchronous RPM, set b5-20= [the number of motor poles]. If another engineered unit, such a fpm or cfm, is desired, set b5-20= xxxxx where X X X X X Digit 5 Digit 4 Digit 3 Digit 2 Digit 1 Digits 1 through 4 set the desired number to be displayed at 100% speed.

Drive Troubleshooting Due to parameter setting errors, faulty wiring, etc., the Drive and motor may not operate as expected when the system is started up. If this occurs, use this section as a reference and apply the appropriate measures. If a fault is displayed on the digital operator, refer to Fault Detection, Table 6.3. If Parameter Cannot Be Set Use the following information if a Drive parameter cannot be set.
Page 192: If The Motor Does Not Operate
If the Motor Does Not Operate Use the following information if the motor does not operate. Ensure the digital operator is securely connected to the Drive. The motor does not operate when the HAND key on the Digital Operator is pressed. The following causes are possible: The Speed Command (Frequency Reference) is too low.
Page 193: The Direction Of The Motor Rotation Is Reversed
The motor stops during acceleration or when a load is connected. The load may be too high. The Drive has a stall prevention function and an automatic torque boost function, but the motor responsiveness limit may be exceeded if acceleration is too rapid or if the load is too great. Lengthen the acceleration time (CI-01) or reduce the load.
Page 194: If The Motor Overheats
If the Motor Overheats Take the following steps if the motor overheats. The load is too high. If the motor load is too high and the motor is used when the effective torque exceeds the motor's rated torque, the motor will overheat.
Page 195: If A Stand Alone Ground Fault Interrupter Operates When The Drive Is Run
If a “Stand Alone” Ground Fault Interrupter Operates When the Drive is Run The Drive performs internal switching, so there is a certain amount of leakage current. This may cause an external ground fault interrupter to operate and cut off the power supply. Whenever possible, use a ground fault interrupter with a high leakage detection level (i.e., a sensitivity current of 200 mA or greater per unit, with an operating time of 0.1 s or more), or one that incorporates high frequency countermeasures (i.e., one designed for use with Drives).
Page 196: If The Motor Rotates Even When Drive Output Is Stopped
If the Motor Rotates Even When Drive Output is Stopped If the motor rotates even when the Drive is stopped, the DC injection braking may be insufficient. If the motor continues operating at low speed, without completely stopping after a stop has been executed, it means that the DC injection braking is not decelerating the motor enough.
