Programmable Monitoring

The G3 has an extensive monitoring system which is employed via the keypad. The information

given in the monitor displays is useful while troubleshooting or commissioning applications.

The following are the possible functions that can be assigned to the four programmable monitors

Value Description Comments

1 Drive compensated output frequency This will be greater than the commanded frequency.

2 Frequency reference This is not necessarily output frequency - drive may be stopped or accel/deceling

3 Output current (output current)2= (torque current)2 + (excitation current)2

4 Input voltage Drive gets from input VAC times 1.73 (will increase during regen).

5 Output voltage

6 Torque current (output current)2= (torque current)2 + (excitation current)2

7 Excitation current (output current)2= (torque current)2 + (excitation current)2

8 PID feedback value Displays the frequency the feedback signal represents

9 Motor OL ratio Example: G3 is rated 150% for 2 min. If you run at 150% for 1 minute, monitor will

10 Inverter OL ratio read “50%”. These monitors represent remaining overload capability. If any monitor

11 DBR OL ratio hits 100%, the drive trips. Drive OL warning starts when drive OL ratio hits 50%

12 Input power In KW

13 Output power In KW

14 RR terminal value Dependent on setting of “RR Input Special Function Select” (1)

15 Peak output current Reset by cycling power, pressing RUN, or resetting drive. Drive keeps track of both

16 Peak input voltage of these values even when not programmed to display as one of the four monitors.

Programming

The following example will make the monitors one through four frequency reference, torque

current, peak input voltage, and peak output current respectively.

Function Select Comments

1 With 10 volts on ‘RR’ terminal, this monitor shows FH. Effective FH is

displayed as ‘RR’ input is changed. Zero volts on ‘RR’ makes effective

FH 30 Hz.

2 Displays acc/dec multiplier. Zero volts on ‘RR’ results in a display of

“1.0”. Ten volts on ‘RR’ results in a display of “10.0”.

3 Displays effective voltage boost. Zero volts on the ‘RR’ terminal results

in a “0.0” display. At ten volts, Voltage Boost is displayed

4 Displays effective Stall Protection Current Level. Minimum is 10%. A

bug: If Current Units Selection in UTILITY PARAMETERS is set to

show current in amps, no units will be displayed with the value in this

monitor.

Binary Input

Introduction

Among the many types of speed reference the G3 can accept is a binary coding. The binary code is based

upon the value of the programmed value of the Maximum Output Frequency (MOF) in the UTILITY

PARAMETERS group. A maximum of seven bits is available to code for the desired speed (ten with the option

board). The speed reference is a sum of digits whose value is the MOF divided by a power of two.

The following example allows a frequency setting resolution of 1 Hz when MOF is 64 Hz. Six bits will be

used. The Reset function will not be available in this scenario. F-CC and ST-CC must be hardwired on the

terminal strip to run.

Terminals S1, S2, S3, S4, RES, and R are assigned the functions of binary bits 10 through 5 respectively.

Binary bits 10 through 5 have reference values of MOF/21, MOF/22, MOF/23, MOF/24, MOF/25, and MOF/26

respectively. In this example, these values are 32, 16, 8, 4, 2, and 1.

open open closed closed open open 8+4 = 12

Notes:

Be careful to connect to “R” and not to “RR”.

You may want to set an unused terminal’s function to “42” (binary data write) to store the frequency

command in the drive’s RAM. The drive will keep running at the speed commanded when the binary

data write was given (i.e. the terminal was shorted to CC) even though the contact closures that coded

for the reference may change.This RAM-written reference is lost when the drive is powered down.

Pattern Run

Introduction

Like the G2/G2+, the G3 has a Pattern Run feature. Pattern Run allows the user to associate a time, direction,

accel/decel time, and volts/hertz pattern with each preset speed. Any seven of the fifteen preset speeds can be

strung together to create a pattern; the G3 stores four such patterns. The number of times a pattern repeats is

programmable from one to infinity.

To run from the keypad, make sure the LOCAL/REMOTE LED is on, then press RUN.

Hit the STOP button after completion to stop blinking LED and allow Pattern Run to be started again.

The drive can store programming for four different pattern runs - each can be remotely run by

programming an input terminal’s function (TERMINAL SELECTION PARAMETERS group) with a

value of 14 (for Pattern Run #1), 15 (for Pattern Run #2), 16 (for Pattern Run #3), or 17 (for Pattern Run

#4).

With normal programming, when a STOP command is given (i.e. ‘F’-’CC’ or ‘R’-’CC’ is opened or

STOP is pressed on the keypad) and the RUN command is remade (i.e. ‘F’-’CC’ or ‘R’-’CC’ is remade or

the RUN button is pressed), the Pattern Run starts over with the first speed. If an input terminal’s function

is programmed to “Pattern Run continue signal” (see value 18 in Guideline 10, Input Terminals), and this

terminal is shorted to ‘CC’, the drive resumes the pattern run at the speed after the speed at which it was

running when the STOP was given. Note: opening and reclosing ‘ST’-’CC’ is not considered a

STOP/RUN command in this scenario; the pattern’s clock keeps ticking. The continue signal must be

active when the pattern is started for correct Continue operation.

Speed #0 in any pattern is only run on the initial pass of the pattern (repeats of pattern don’t include Speed

#0) Press the MON button during the run to see the special information displayed during Pattern Run.

* If Preset Speed Mode Activation is set to “0”, the drive ignores direction, accel/decel times, and V/Hz

programmed into Preset Speed n Operating Mode and looks for direction and/or ACC/DEC and/or V/Hz

from terminal strip.

** With this parameter set to “5” and an input terminal’s function set to “19” (“Pattern Run step signal” ;

see Guideline 10, Input Terminals), the drive steps through the pattern’s speeds every time a momentary

contact closure is made to ‘CC’. Any programmed speed time is ignored.
