5–22 Programming
[Speed Control]
This parameter selects the type of speed modulation
active in the drive.
This parameter cannot be changed while the drive is
running.
Important: If encoder feedback closed loop speed
regulation is required, “Encoder Fdbk” must be
selected.
Parameter Number 77
Parameter Type Read and Write
Factory Default “Slip Comp” (“No Control” frn < 4.01)
Units Display Drive
“No Control” 0
Frequency regulation
“Slip Comp” 1 Slip compensation
“Speed Droop” 2 Negative slip compensation
“PLL” 3 Phase lock loop (requires frn < 4.01)
“Encoder Fdbk” 4 Encoder feedback–closed loop
“Droop + Reg” 5 Enc. fdbk.–closed loop w/ active droop
“P Jump” 6 Traverse function
“Process PI” 7 Closed loop PI control
[Slip @ F.L.A.]
This value sets the amount of automatic increase or
decrease to the drive output to compensate for
motor slip. When [Speed Control] is set to “Slip
Comp”, a percentage of this value proportional to
output current is added to the drive output
frequency. When [Speed Control] is set to “Droop”, a
percentage of this value proportional to output
current is subtracted from the drive output
frequency.
Parameter Number 42
Parameter Type Read and Write
Display Units / Drive Units 0.1 Hertz / Hertz x 10
Factory Default 1.0 Hz (0.0 Hz frn < 4.01)
Minimum Value 0.0 Hz
Maximum Value 10.0 Hz (5.0 frn<4.01)
[Slip Comp Gain]– Firmware 4.01 & later
This parameter is the gain for the slip compensation
and adjusts the recovery rate after a load change.
Parameter Number 195
Parameter Type Read and Write
Display Units / Drive Units None
Factory Default 1
Minimum Value 1
Maximum Value 40
[Run On Power Up]
This parameter enables the function that allows the
drive to automatically restart on Power Up. This
parameter requires that a two wire control scheme
be installed at TB3 and that a valid start contact be
present. Refer to Input Mode Selection figure in
Chapter 2.
Parameter Number 14
Parameter Type Read and Write
Factory Default “Disabled”
Units Display Drive
“Disabled” 0
“Enabled” 1
ATTENTION: This parameter may only be used as outlined in
NFPA79, paragraph 6-14 (exceptions 1-3) for specialized
applications. Equipment damage and/or personal injury may
result if this parameter is used in an inappropriate application.
!
[Reset/Run Tries]
This value sets the maximum number of times the
drive attempts to reset a fault and restart before the
drive issues a “Max Retries Fault”. See Chapter 6 for
a list of resettable faults.
Parameter Number 85
Parameter Type Read and Write
Display Units / Drive Units 1 Try / Tries
Factory Default 0
Minimum Value 0
Maximum Value 9
