T076 [Analog In 2 Loss]
Related Parameter(s):
Stop drive before changing this parameter.
Selects drive action when an input signal loss is detected. Signal loss is defined as an analog signal
less than 1V or 2mA. The signal loss event ends and normal operation resumes when the input signal
level is greater than or equal to 1.5V or 3mA. If using a 0-10V analog input, set
[Analog In 2 Lo]
to a minimum of 20% (i.e. 2 volts).
The drive will fault on an F29
when the analog signal is lost if this parameter is used
for the PID feedback, and this parameter and
[PID Ref Sel] are both set to an option other than
0 “Disabled”.
Options
0 “Disabled” (Default)
1 “Fault (F29)”
F29 Analog Input Loss
2 “Stop”
Uses P037 [Stop Mode]
3 “Zero Ref”
Drive runs at zero speed reference.
4 “Min Freq Ref”
Drive runs at minimum frequency.
5 “Max Freq Ref”
Drive runs at maximum frequency.
6 “Preset Freq0”
Drive runs at A143 [Preset Freq 0].
7 “Hold Last” (with FRN
6.xx and later)
Drive uses last frequency command from analog input prior to
signal loss, or last PID reference prior to signal loss when
used as a PID reference.
T077 [Sleep-Wake Sel]
Related Parameter(s):
The drive “sleeps” if the appropriate analog input drops below the set [Sleep Level] for the time set in
[Sleep Time] and the drive is running. When entering sleep mode the drive will ramp to zero and the
run indicator (
) on the keypad display will flash indicating the drive is in “sleep” mode.
When the appropriate analog input rises above the set [Wake Level] the drive will “wake” and ramp to
the commanded frequency.
Inversion can be accomplished by setting T078 [Sleep Level] to a higher setting than T080 [Wake
Level].
Options
0 “Disabled” (Default)
1 “Analog In 1”
Sleep and Wake enabled from Analog Input 1.
2 “Analog In 2”
Sleep and Wake enabled from Analog Input 2.
3 “Command Freq”
Sleep and Wake enabled based on drive commanded
frequency.
4 “Ind Slp Wake” (with
FRN 7.xx and later)
Sleep and Wake enabled independently using parameters
T090 [Sleep Sel] and T091 [Wake Sel].
ATTENTION:
Enabling the Sleep-Wake function can cause unexpected machine
operation during the Wake mode. Equipment damage and/or personal injury can result if
this parameter is used in an inappropriate application. In addition, all applicable local,
national & international codes, standards, regulations or industry guidelines must be
considered.
