F347

F349

Creeping Time

Program Torque Torque Control

Once the Creep function of F346 is activated, this parameter determines the duration of activation of the Creep function.

Direct Access Number — F347

Parameter Type — Numerical

Factory Default — 0.10

Changeable During Run — Yes

Minimum — 0.0

Maximum — 2.50

Units — Seconds

Braking Time Learning Function

Program Torque Torque Control

This parameter is used to establish approximate settings for parameters F343, F345, F346, and F347.

Direct Access Number — F348

Parameter Type — Selection List

Factory Default — Disabled

Changeable During Run — Yes

Note: Setting this parameter should be done using a light load only.

Set this parameter to Brake Signal Learning. Provide a Run command. The aforementioned parameters will receive approximate values. Application- specific adjustments may be required when done.

Settings:

0 — Disabled

1 — Enabled

Accel/Decel Suspend

Direct Access Number — F349

Program Fundamental Accel/Decel #1 Settings

Parameter Type — Selection List

To maintain a constant speed setting while running, this parameter may be used

Factory Default — Off

Changeable During Run — Yes

to suspend speed changes for a user-set length of time.

 

The Accel/Decel Suspend function is enabled by setting this parameter to

 

either Terminal Board Input or to F350 F353.

 

Selecting Terminal Board Input at this parameter requires that a discrete input

 

terminal be set to Dwell Signal (see Table 5 on pg. 236 for a listing of available

 

settings). Upon activation of the Dwell Signal terminal the output frequency

 

remains at the at-activation speed for the duration of the activation. When

 

deactivated the programmed accel or decel ramp resumes.

 

Selecting F350 F353 at this parameter requires that the acceleration and/or

 

the deceleration Suspend Frequency and Suspend Time settings be completed

 

at F350, F351, F352, and F353. Upon reaching the frequency setting of F350

 

(Accel) or F352 (Decel), the Accel/Decel ramp will cease and the output

 

frequency will hold at the threshold frequency setting for the time setting of

 

F351 for Acceleration or F353 for deceleration.

 

Settings:

 

0 — Off

 

1 — F350 F353 Settings

 

2 — Terminal Board Input
