This document is supplied with Model KBMG only.

Warning! Before installing the SIMG onto the KBMG, the AC power must be disconnected.

The following Installation and Wiring instructions are to be used as a supplement to the KBMG Installation and Operating Instructions Manual (Part No. A40263). Refer to the SIMG Installation and Operating Instructions Manual (Part No. A40269) for specific and external signal following connections. See Figures 1 - 5, on page 2.

Tools required for installation: small flat blade screwdriver, long nose pliers, cutters.

Notes: 1. To install the SIMG, be sure the Top Panel of the KBMG 2-Piece Finger-Safe Cover (FSC) is not installed. 2. All trimpots and jumpers, on the KBMG, must be set before installing the SIMG.

1Preparing the KBMG Prior to Installing the SIMG - See Figure 1.

1.1Insert the flat blade screwdriver between the KBMG PC Board and Terminal Block TB1 and gently pry it off. Discard the Terminal Block.

Note: When prying off the Terminal Block, care should be taken to not scratch circuit traces that are on the PC Board surface.

1.2Using a flat blade (or Phillips) screwdriver, remove the screw from the KBMG FSC. Retain this screw for use in Section 3.3, below.

1.3Using long nose pliers, remove and discard the Terminal Boots that are factory installed on Terminals "F-" and "F+" on the KBMG.

2Preparing the SIMG for Installation onto the KBMG - See Figure 2.

Note: If the SIMG does not contain a Ring Lug and Cable Tie, proceed to paragraph 3 below.

2.1Using long nose pliers, carefully uncurl the Ring Lug off the Cable Assembly.

2.2Using cutters, carefully remove the Cable Tie from the SIMG.

2.3Discard the Ring Lug and Cable Tie.

3Installing the SIMG onto the KBMG - See Figure 3.

3.1Align and gently push the Terminal Block on the SIMG onto the Terminal Block Header on the KBMG.

3.2Align the (3) Holes on the SIMG with the (3) Snap Posts on the KBMG FSC. Gently press the SIMG Board onto the (3) Snap Posts. Apply pressure at each Snap Post.

3.3Install the Screw, that was removed in Section 1.2, and gently tighten it to secure the SIMG onto the KBMG FSC. Do not overtighten.

4Wiring the SIMG After Installed onto the KBMG - See Figures 4 and 5.

Note: On older SIMG models, the Brown and Yellow Wires must be crisscrossed, as shown in Figure 3. On newer SIMG models, the Brown and Yellow Wires are not crisscrossed.

4.1Carefully insert the Cable Assembly through the Retainer Clip on the KBMG FSC.

4.2Connect the Brown Wire (larger terminal) to Terminal F- on the KBMG.

4.3Connect the Yellow Wire (smaller terminal) to Terminal F+ on the KBMG.

5Installing the SIMG Finger-Safe Cover - See Figure 3.

Align the (4) Snap Tabs on the SIMG FSC with the (4) slots on the KBMG FSC. The Cable Shroud must be positioned over the Cable Assembly (Brown and Yellow Wires). Apply pressure to snap the cover into position.

Note: Be sure that the Cable Assembly is centered in the Retaining Clip so the wires are not damaged by the Cable Shroud.

The SIMG Installation is now complete.

i. KBMG-212D SIMPLIFIED OPERATING INSTRUCTIONS

IMPORTANT – You must read these simplified operating instructions before you proceed. These instructions are to be used as a reference only and are not intended to replace the detailed instructions provided herein. You must read the Safety Warning before proceeding.

1.CONNECTIONS.

A.AC Line – Wire AC line voltage to terminals L1 and L2. Be sure jumpers J1A and J1B are both set to the correct input line voltage 115 or 230 VAC. Connect ground wire (earth) to green ground screw.

B.Motor.

1.Permanent Magnet (PM Type). Connect motor armature leads to M1(+) and M2 (–). Be sure jumper J3 is set to the proper position “A90" for 90 volt DC motors and “A180" for 180 volt DC motors. Note: 180 volt DC motors must be used with 230 VAC line, 90 volt motors can be used with a 230 VAC or 115 VAC line.

Note: Motor performance and efficiency, including brush life, can be adversely affected when using 90 volt motors with a 230 VAC line. Contact motor manufacturer for derating information.

2.Shunt Wound Motors. Connect motor armature leads as above. Connect full voltage shunt field leads (90 volt motors with 100 volt fields and 180 volt with 200 volt fields) to F+ and F-. Connect half voltage field leads (90 volt motors with 50 volt fields and 180 volt motors with 100 volt fields) to F+ and L1.

1

2.MOTOR CURRENT.

Jumper J2 is factory set for 7.5 amp motors (7.5A). For lower amperage motors, place J2 in the proper position. If motor amperage is less than 1.7 amps, use the 1.7 amp position and readjust the IR and CL trimpots according to section VII, C and D on pages 28 and 29. Note: The factory setting for Current Limit is 150% of the nominal current setting (e.g., if J2 is selected for 5 amps, the actual CL setting will be 7.5 amps). Note: If the 10.0 amp setting (10.0A) is required, an auxiliary heatsink (KB P/N 9861) must be used.

3.TRIMPOT SETTINGS.

All trimpots have been factory set in accordance with figure 12, p. 20.

4.ENABLE.

A jumper must be connected between “EN” and “COM” terminals or control will not operate. (See sec. V, G, page 22.)

Note: For the location of jumpers and trimpots, see fig. 12, control layout, on page 20.

5.SPEED OR TORQUE MODE.

Jumper J5 is factory set for speed control operation (SPD). For torque control, set J5 to the “TRQ” position.

This product complies with all CE directives pertinent at the time of manufacture. Contact factory for detailed installation instructions and Declaration of Conformity. Installation of a CE approved RFI filter (KBRF-200A, KB P/N 9945C or equivalent) is required. Additional shielded motor cable and/or AC line cables may be required along with a signal isolator (model SIMG, KB P/N

8832 or equivalent).

I.GENERAL INFORMATION.

The KBMG-212D is a full-wave regenerative control, capable of operating a DC motor (Permanent Magnet or Shunt) in a bidirectional mode. It provides 4-quadrant operation which allows forward and reverse torque in both speed directions. The drive offers excellent controllability, which closely approximates the performance of servo-type drives. Ratings and specifications are presented in tables 1 and 3. Be sure the drive is used within these ratings and specifications.

(Note: Regenerative drives normally produce more motor heating than standard unidirectional SCR speed controls, especially under low speed operation. This should be taken into consideration when specifying motor rating.)

WARNING! Be sure to follow all instructions carefully. Fire or

electrocution can result due to improper use of this product. Read Safety Warning.

II.OPERATION.

The KBMG-212D will vary motor speed or torque as a function of the signal voltage on input terminals “SIG" (signal) and “COM” (common). The input voltage can be derived from the wiper of the main speed potentiometer or from an isolated analog input (signal voltage following mode). Since the KBMG-212D is a 4-quadrant regenerative drive, the motor speed will follow both a positive and negative signal voltage and drive the motor in both the forward direction and reverse direction. In addition, it will apply both forward and reverse torque in order to stabilize motor speed.

5

To understand the concept of a regenerative drive, the operation of an elevator can be used. If one were to enter the elevator on the first floor and press 10, the motor and control would have to lift the elevator against gravity. In this mode, the drive would operate like a conventional speed control which is called “motoring” (the applied load is opposite to the direction of motor rotation). When the elevator is at floor 10 and floor 1 is pressed, gravity will try to pull the elevator car down faster than the speed for which it is set. The control will then provide reverse torque to keep the car from falling faster than the set speed. This operation is regeneration (the applied load is in the same direction as the direction of motor rotation).

The table below summarizes the different modes of operation.

III.SETTING SELECTABLE JUMPERS.

The KBMG-212D has customer selectable jumpers which must be set before the control can be used (refer to fig. 1, p. 10). Bold indicates factory setting. See fig. 12, p. 20 for location of jumpers.

A.J1A, J1B – Input AC Line Voltage – Select proper input line voltage, 115VAC or 230VAC, by placing both J1A and J1B in the correct corresponding position, “115" or “230.” (See fig. 1, p. 10.)

B.J2 – Armature Current – Select the J2 position (1.7, 2.5, 5.0, 7.5, 10) closest to the rated motor current. (Note: The maximum output current is set to 150% of the J2 position, which may be readjusted using the FWD CL and REV CL trimpots.)

C.J3 – Motor Armature Voltage – Select the desired armature voltage by placing J4 in the proper position, “A90" or “A180.” Note: For 115 volt AC line input, J3 must be set to “A90.” For 230 input, the armature voltage is normally set for “A180.” However, it is also possible to set the armature voltage to “A90" for stepdown operation. (See fig. 2 and table 5 on page 10.)

J3 – Tach-Generator Feedback (for use with 1800 RPM motors.) – Jumper J3 is also used if tach-generator feedback is to be used. (See fig. 2, p. 10) If a 7 volt per 1000 RPM tach-generator is used, set jumper J4 in the “T7" position. For a 50 volt per 1000 RPM tach-generator, set the jumper in the “T50" position. Note: When using tach-generator feedback, the IR Comp trimpot should be turned to a minimum setting (full CCW).

position for potentiometer operation. If the control is to be operated from an isolated 0 – ±10VDC signal (see sec. V, F, p. 22.), set J4 to the “10V” position.

E.J5 – Control Mode (Speed or Torque).

i. Speed (SPD) Mode – (Note: Factory setting of J5 is Speed mode.) In the speed

control mode (J5 set to SPD), the KBMG-212D will provide variable speed control. The motor speed

will be in direct proportion to

the input signal. Both forward and reverse torque are used to stabilize motor speed. (See fig. 6, p. 13.)

ii.Torque (TRQ) Mode – In the torque control mode (J5 set to TRQ), the KBMG-212D will vary the maximum motor torque as a function of the voltage input to terminals “SIG” (signal) and “COM” (common). This voltage can be derived from the wiper of the main potentiometer or from an isolated analog input (signal voltage following).

11

If the motor torque is greater than the load torque, the motor will rotate. If no load is applied to the motor, the motor will rotate at a speed proportional to the torque setting as set by the main potentiometer (see fig. 7, p. 14). By using the ACCEL and DECEL trimpots, the application of torque can be made more gradual or less gradual as required by the application. A maximum torque can be established using the current selector jumper, J2, which can be further modified by using the FWD and REV CL trimpots.

F. J6 – Coast to Stop (CTS), FIG. 5 – JUMPER J6 SETTING Regenerate to Stop (RTS)

This function operates in

conjunction with the Enable circuit, which is used to start and stop the control electronically. If the circuit connecting terminals “EN” and “COM” on terminal block TB1

are opened, the control will cause the motor to stop. When jumper J6 is in the factory position (RTS), the motor will regenerate to a stop.

If J6 is changed to the coast to stop (CTS) position, the motor will coast to a stop when the “EN” - “COM” circuit is opened.

Note: Control will not run unless a jumper or closed contact is connected between the “EN” and “COM” terminals.

IV. MOUNTING.

Mount the KBMG-212D on a flat surface in an atmosphere free of moisture, metal chips, and corrosion. See Mechanical Specifications, fig. 13, p. 21. A 5K ohm remote speed potentiometer is provided with each control. Install potentiometer using hardware provided. Be sure to install insulating disk between potentiometer and inside of front panel.

Enclosure – When mounting the KBMG-212D in an enclosure, it must be large enough to allow the proper heat dissipation. A 12"12"12" enclosure is suitable when the control is not mounted on an auxiliary heatsink. A 12"12"24" enclosure is appropriate at full rating (11.0 amps) when the control is mounted on an auxiliary heatsink KB P/N 9861.

V.WIRING. Warning! Read Safety Warning before attempting to use this control.

Warning! To avoid erratic operation do not bundle AC line and motor wires with potentiometer, voltage following, enable, inhibit or other signal wiring. Use shielded cables on all signal wiring over 12" (30 cm) – Do not ground shield.

Wire control in accordance with National Electrical FIG. 8 – AC LINE CONNECTION Code requirements and other local codes that

apply. A “normal blo” 20 amp fuse or circuit breaker should be used on each AC line conductor

that is not at ground potential (do not fuse neutral or grounded conductors). (See section VI, p. 24 for

fuse information.) Wire control in accordance with connection diagrams (see figures 8, 9, 10A, 10B, 11 and 14 on pages 16, 17, 19 and 22). A separate AC line switch or contactor must be wired as a disconnect switch so

that contacts open each ungrounded conductor of the control. See table 6 for terminal block wiring information.

E.Main Speed Potentiometer – The main speed potentiometer can be connected in several ways using terminals “COM,” “+15,” “SIG” and “–15.” A 5K ohm potentiometer is supplied with control. (A 10K potentiometer can also be used.)

(Warning! Terminals “COM,” “+15,” “SIG” and “–15" are not isolated from AC line.) Note: Jumper J4 must be in the “15V” position.

i.Unidirectional operation only – Connect potentiometer to terminals “COM,” “+15,” “SIG" for forward direction. To operate in reverse direction, connect to “COM,” “SIG,” and “–15.” See fig. 11, p. 19.

ii.Bidirectional operation only – Connect to terminals “COM,” “+15,” “SIG,” and “–15" when using reversing contacts. To operate with a potentiometer, connect to “+15," “SIG,” and “–15." See fig. 11.

F. Voltage Following – An isolated analog voltage can be used in lieu of main speed potentiometer.

Connect signal to terminals “SIG" and “COM.” Note: Terminal “COM" is common. A positive signal to terminal “SIG” will produce a positive output to motor. A negative signal to terminal “SIG" will produce a negative output. A 0 to ±10VDC is required to operate control from 0 ± full

output. Note: Jumper J4 must be

in the “10V” position. Note: An isolated signal voltage must be used or catastrophic failure can result. (A bipolar signal isolator, model SIMG [KB P/N 8832], is available as an option from your distributor.)

G.Enable Start/Stop Circuits – The KBMG-212D contains a 2-wire stop circuit (Enable), which is used to electronically bring the motor to a “stop.” An isolated single contact closure is required. If an isolated contact is not available, it may be necessary to use an isolation relay.

*Note: If 2-wire start/stop circuit is not used, a jumper must be wired to EN and COM or control will not operate.

WARNING! Do not use Start/Stop or Enable functions as a safety disconnect. Use only an AC line disconnect for that purpose.

22

i.Regen to a stop using terminals EN and COM on terminal block TB1 –

When a contact is opened between terminals “EN” and “COM,” with jumper J6 in the “RTS” position, the motor will regeneratively brake to a rapid stop. Application note (See fig. 15): If controlled regen to stop is required, a contact can be installed in series with the signal “SIG” connection. The braking time will be equal to the REV ACCEL setting when the motor is in the forward direction, and equal to the FWD ACCEL setting when the motor is in the reverse direction. Note: J4 must be in the “15V” position. (See fig. 11D, p. 19.)

ii.Coast to a stop using terminals “EN” and “COM” on terminal block TB1 –

If coast to stop operation is required, move jumper J6 to the coast to stop (CTS) position. When the contact is opened between “EN” and “COM,” the motor will coast to a stop. See fig. 16.

H.Tach-generator Feedback – The KBMG212D is factory set for armature feedback, which provides good load regulation for most applications. For superior load regulation, analog tach-generator feedback can be used.

FIG. 17 – TACH-GENERATOR

FEEDBACK

Wire the tach-generator so that the polarity of

the tach-generator is the same with respect to the input signal polarity (see fig. 17).

Note: If tach-generator is wired with reverse polarity, the motor will run at full speed. Note: Jumper J3 must be set to the proper

position for tach feedback. See sec III, C, p. 9 and fig. 2 on page 10. Note: Check tach voltage polarity with respect to input signal if polarity does not match reverse tach leads.

Be sure AC line is disconnected when rewiring tach-generator.

VI. FUSING.

Armature Fuse – It is recommended that the correct size armature fuse be installed, depending on the rating of the motor and form factor (RMS/AVG current). Fuse type should be Littelfuse 326 ceramic or Buss ABC, or equivalent. A fuse chart is presented below which suggests appropriate armature fuse ratings. However, the specific application may require larger fuse ratings based on ambient temperature, CL set point and duty cycle of operation (see table 8, p. 25). Fuses may be purchased from your distributor. Wire fuse in series with armature lead.

VII. TRIMPOT ADJUSTMENTS.

The KBMG-212D contains trimpots that have been factory adjusted for most applications. See specifications for factory settings. (Note: Fig. 12, p. 20, presents the various trimpots with their location. They are shown in the approximate factory position.) Some applications may require readjustment of trimpots in order to tailor control to exact requirements. Readjust trimpots as follows:

The REV ACCEL trimpot determines the amount of time it takes the control

voltage to reach full output in the reverse direction and the time it takes for the control voltage, in the forward direction, to reach zero output. (REV ACCEL is the Forward Decel.)

The FWD and REV ACCEL trimpots are factory adjusted to approximately 1 second. The acceleration times are adjustable over a range of 0.1 to 15 seconds. See fig. 18 for graphical representation of ACCEL.

Note: The FWD and REV CL trimpots may override the rapid accel and decel settings.

B. Dead Band Trimpot (DB) –

The DB trimpot sets the amount of main speed potentiometer rotation or analog voltage input required to initiate control voltage output. It is factory adjusted to approximately 25% of rotation.

The DB trimpot also determines the amount of delay that will occur before regeneration starts. Regeneration occurs when the applied load torque is in the same direction as the motor rotation.

To readjust the DB to factory setting:

i.Set Main Speed pot to zero speed position.

ii.Set DB trimpot to full CCW position.

27

iii.Adjust DB trimpot CW until motor hum is eliminated. (See fig. 19, p. 27 for graphic illustration of the DB trimpot.) Note: If the dead band trimpot is set too low (CCW direction), the motor may oscillate between forward and reverse. Adjust dead band trimpot CW until the instability disappears. (Oscillation may also occur due to RESP and IR COMP trimpot settings. See sec. VII, D & F on page 29.)

C.Forward Current Limit (FWD CL) and Reverse Current Limit (REV CL) Trimpots – These trimpots are used to set the maximum amount of DC current that the motor can draw in both the forward and reverse directions. The amount of DC current determines the amount of maximum motor torque. They are factory set at 150% of the current established by the jumper J2 setting.

Readjust the CL trimpot as follows:

i.Turn CL trimpot to MIN (CCW) position. Be sure jumper J3 is in the proper position approximately equal to the motor DC ampere rating.

ii.Wire in a DC ammeter in series with armature lead. Lock shaft of motor.

iii.Apply power. Rotate CL trimpot quickly until desired CL setting is reached (factory setting is 1.5 times rated motor current). Be sure control is in forward direction for FWD CL trimpot adjustment and likewise with REV CL.

Warning! To prevent motor damage, do not leave motor shaft locked for more than 2 – 3 seconds.

Caution! Adjusting the CL above 150% of motor rating can cause overheating and demagnetization of some PM motors. Consult motor manufacturer.

28

D.IR Compensation (IR Comp) – The IR Comp is used to stabilize motor speed under varying loads. Readjust the IR Comp trimpot as follows:

i.Initially set trimpot to factory position (approximately 10 o’clock).

ii.Run motor at approximately 30 – 50% of rated speed under no load and measure actual speed.

iii.Load motor to rated current. Rotate IR Comp trimpot so that loaded speed is the same as the unloaded speed measured in the previous step.

Control is now compensated so that minimal speed change will occur over a wide range of motor load. Note: Excessive IR Comp will cause unstable (oscillatory) operation.

E.Maximum Speed (MAX) – The MAX trimpot is used to set the maximum output voltage of the control which, in turn, sets the maximum speed of the motor.

Adjust the MAX trimpot as follows:

i.Rotate Main Speed potentiometer to full speed (CW).

ii.Adjust MAX trimpot to desired maximum motor speed.

Note: Do not exceed maximum rated RPM of motor since unstable operation may result.

F.Response Trimpot (RESP) – This trimpot determines the dynamic response of the control. The factory setting is approximately 50% of full rotation. The setting may be increased if a faster response is required. Note: If response is set too fast, unstable operation may result.

29

VIII. FUNCTION INDICATOR LAMPS.

A.Power On (PWR ON) – Indicates that the drive is energized with the AC line.

B.Overload (OL) – Indicates the control has reached the current limit set point which has been established by the position of jumper J2 and the FWD CL and REV CL trimpot settings. In transient load applications, it is normal for this light to blink.

IX. KBMG-212D ACCESSORIES
