Programming Parameters

7-36

Parameter 620 – System Reset Select [Sys Reset Select]

Internal units : None
Programming Terminal units: None
Minimum Value: 0
Maximum Value: 1
Default Value: 0

Description: This parameter determines whether terminal TB3–3
provides the System Reset function or the Logic Command Stop
function. The choices are:

0 = System Reset

1 = Normal Stop

The System Reset function requires a Normally Open operator device
which closes to cause a reset. A reset then allows the 1395 to
perform its power up sequence. Any data not previously stored in
EEPROM will be lost.

The Logic Command Normal Stop function requires a Normally
Closed operator device. When opened, the drive will stop. The stop
method (ramp stop, coast stop, regen stop, etc.) will be determined by
the setting of Parameter 624 (maintain start) and the logic command
parameter that has control of the Drive.

Parameter 621 – Feedback Device Type [Fdbk Device Type]

Internal units : None
Programming Terminal units: None
Minimum Value: 0
Maximum Value: 2
Default Value: 1

Description: Is the selected source for motor velocity feedback.
Choices are:

0 = Encoder feedback.

1 = Armature voltage feedback. This limits the motor speed
application to base speed or less.
Note: Setting this value to 1 will not limit the motor to base speed or
less. This value must be used with parameters 607/608 to properly
configure the top motor speed.

2 = Analog tachometer feedback. When choosing this function, an
analog input should be linked to Parameter 156 (Tach Velocity).

3 = No feedback device in use. This will disable the speed regulator
and tach loss fault detection. This is used in torque mode
applications.
