DESCRIPTION

RUN MODE

Tachometer display calibrated in user units, with decimal point. Actual Speed is calculated as:

(Feedback Frequency"," Full Scale Frequency) x Full Scale Speed

and is updated once per second.

Desired Speed in user units, with decimal point. Can be changed while running using the

Right cursor, Increment, and Decrement key (see page 5) if Front Panel Lock (line 10) is set to

Off. The Speed Setpoint will not be allowed to go above the Full Scale Speed value.

Value of the Error Counter shows difference between internally generated speed reference and

actual feedback device. Reset to zero when Trim Reset input is active (open loop operation).

Amount of Errorapplied-to output to correct for differences between Speed Setpoint and Actual

Speed. Correction is (±Error Counts X Gain), in units of 0 to A bits (10 mV/bit).

PROGRAM MODE - - - - - - - - - - - -

Entered by pressing the RUN/PGM Key when the PGM DIS switch is Off (down position).

Accel and Decel rate for changes to the Speed Setpoint and for Run/Stop transitions. Ramp is

in units of Speed LSDs per second. (For example, changing the Speea Setpoint from 850 to

875, a change of 25 RPMs, will take 5 seconds if the Ramp Rate is set to 5 RPMs per second.)

Value of Alarm Setpoint in feedback pulses. When the Error Counter

Error Alarm, the Error

Alarm output is turned on. May be used to indicate excessive lag or loss of feedback. (To test

the Error Alarm output, set the Alarm to zero; the output should turn on immediately.)

Maximum running speed, in user units, which corresonds to full output applied to drive. (To

provide operating headroom, set the Full Scale Speed about 10% higher than what is actually

needed -

e.g. set to 1980 for an 1800 RPM range.) Decimal Point setting for speed displays

is also selected on this line.

Allows drive and encoder checkout by applying a voltage to the drive and monitoring the

feedback frequency. The Right cursor selects the 0 to A function, which can be ramped from

to 99% output. The next Right cursor displays the feedback frequency in Hz.

Maxmimum feedback encoder frequency when full output is applied to the drive. (To provide

headroom, measure the frequency when 90% output is applied.) This number can also be

calculated by [ (maximum encoder shaft RPM

60) X (encoder resolution in PPR) ].

FRONT PANEL LOCK

Front Panel changes to the Speed Setpoint and Error Gain are disabled by selecting On, or

enabled by choosing Off with the Right cursor. Does not effect Program Mode editing.

ADJUST INPUT

Select type of external setpoint adjustment. Set to Up/Down for use with Increase and

Decrease contacts for ramping the setpoint up or down; or Bidirectional for connection to a

quadature output Panelcoder (provides incremental up and down changes).

Set to determine resolution and speed of the external setpoint adjustment device. Each

quadrature cycle will change the Speed Setpoint by 4X the Adjust Rate (Pot operation). The

Speed Setpoint will change by the Adjust Rate amount for each second the Increase or

Decrease contacts are active (Mop operation).

These features provide an easily accessible method of checking the operation of the product

and external connections for proper operation. The error codes listed on page 3 diagnose

additional problems which may not be permanent malfunctions.

Display of active signal and control inputs. The indicators Rand b are given when the

Signals A and B, respectively, are driven with a high input. The prompts f and

are given

when Inputs 1 and 2, Ramp Hold and Trim Reset, respectively, are driven with a low input.

Display of active keyboard buttons. The indicators

',d, P,

and [

are present when the

Increment/On, Decrement/Off, Run/Program, and Reset/Clear keys, respectively, are pressed.

The display shows a constant pattern to verify that each display digit is functioning.

All display digits and annunciators are illuminated to verify proper operation.
