Parameter

 

 

Description

 

 

 

 

 

 

 

 

PROCESS

 

Follow I:O Out

 

 

Only used for serial communications. In master/follower configurations this parameter

CONTROL

 

 

 

 

represents the follower portion of the ratio. The master portion of the ratio is set in the

Continued

 

 

 

 

Follow I:O Ratio parameter.

 

 

 

 

 

Note: When using Serial Commands, the Follow I:O Ratio parameter value must

 

 

 

 

 

be set using two separate parameters: Follow I:O Ratio and Follow I:O Out.

 

 

 

 

 

The follow I:O Ratio sets the Input (Master) part of the ratio and Follow I:O

 

 

 

 

 

Out sets the output (Follower) part of the ratio. For example, a 2:1

 

 

 

 

 

(input:output) ratio is set by a Follow I:O Ratio value of 2 and a Follow I:O

 

 

 

 

 

Out value of 1.

 

 

 

 

 

Note: The encoder lines parameter must be defined if a value is entered in the

 

 

 

 

 

Follow I:O Ratio parameter.

 

 

Encoder Lines

 

 

Only used if an optional master pulse reference/isolated pulse follower expansion board

 

 

 

 

 

is installed. Defines the number of pulses per revolution of the master encoder. This

 

 

 

 

 

parameter defines the output master pulse rate for a downstream follower drive.

 

 

Integrator Clamp

 

 

Allows limiting (clamping) of the PID integrator. The clamp is set as a percentage of

 

 

 

 

 

maximum motor speed. For example, a setting of 10% (assuming an 1800 RPM motor)

 

 

 

 

 

means the integrator will not contribute more than 180 RPM to the total output demand

 

 

 

 

 

of the PID loop.

 

 

Minimum Speed

 

 

Set the minimum demand for the PID output. For example, a setting of 10Hz means the

 

 

 

 

 

output demand from the PID will never decrease below this setting (even if the process

 

 

 

 

 

error is zero). Minimum speed is active for unipolar as well as bipolar applications.

 

 

 

 

 

 

SKIP

 

Skip Frequency (#1,

 

 

The center frequency of the frequency band to skip or treat as a dead-band. Three

FREQUENCY

 

#2 and #3)

 

 

bands can be defined independently or the three values can be selected to skip one

 

 

 

 

 

wide frequency band.

 

 

Skip Band

 

 

The width of the band centered about the Skip Frequency. For example, if Skip

 

 

(#1, #2 and #3)

 

 

Frequency #1 is set to 20Hz and Skip Band #1 is set to 5Hz, continuous operation is

 

 

 

 

 

not allowed in the dead-band of 15Hz to 25Hz.

 

 

 

 

 

 

SYNCHRO

 

Synchro Starts

 

 

Synchronizes motor and load speed when the motor shaft is rotating at the time the

STARTS

 

 

 

 

inverter applies power to the motor. If set to Restarts Only, allows Synchro Starts

 

 

 

 

 

after a fault condition is reset. If set to All Starts, allows Synchro Starts at all fault

 

 

 

 

 

resets as well as restarts after power failure or after a run command.

 

 

Sync Start Frequency

 

 

Allows the Synchro Start feature to begin scanning motor rotational frequency at the

 

 

Sync Scan V/F

 

 

MAX Frequency or a SET Frequency.

 

 

 

 

Sets the Volts/Hertz ratio for the Synchro Start feature as a percentage of the V/Hz ratio

 

 

 

 

 

 

 

 

 

 

defined by the Max Output Volts/Base Frequency. This Sync Scan V/F percentage

 

 

 

 

 

value is multiplied by the Max Output Volts/Base Frequency value. If this value is too

 

 

Sync Setup Time

 

 

high, the inverter may fault on Over-current.

 

 

 

 

The time for the inverter to ramp the output voltage from zero to the voltage that

 

 

 

 

 

 

 

 

 

 

corresponds to the Sync Start Frequency. A 0.5 second delay before the ramp

 

 

 

 

 

begins is not included in this time. If the Synchro Start feature is not operating quickly

 

 

Sync Scan Time

 

 

enough, decrease the Sync Setup Time value.

 

 

 

 

The time allowed for Synchro Start to scan and detect rotor frequency. Scanning begins

 

 

 

 

 

 

 

 

 

 

at the Sync Start Frequency to 0Hz. Generally, the shorter the Sync Scan Time the

 

 

 

 

 

more likely a false Synchro Start will be detected. This value should be set high

 

 

Sync V/F Recover

 

 

enough to eliminate false Synchro Starts.

 

 

 

 

The time allowed to ramp up the output voltage from the Synchro Start scan voltage to

 

 

 

 

 

 

 

 

 

 

the normal output voltage. This occurs after the synchronization frequency is

 

 

 

 

 

detected. This parameter value should be low enough to minimize Synchro Start time

 

 

Sync Direction

 

 

without causing the inverter to fault on Over-current.

 

 

 

 

Allows Synchro Starts in either or both motor rotational directions. If the application

 

 

 

 

 

 

 

 

 

 

requires motor shaft rotation in one direction only, scanning in that direction only will

 

 

 

 

 

minimize Sync Scan Time.

 

 

 

 

 

 

COMMUNICATIO

 

Protocol

 

 

Sets the type of communication the control is to use, RS-232 ASCII (text), RS-485 ASCII

NS

 

 

 

 

(text), RS-232 BBP, or RS-485 BBP protocols.

 

 

Baud Rate

 

 

Sets the speed at which communication is to occur.

 

 

Drive Address

 

 

Sets the address of the control for communication.
