Programming and Parameters Chapter 3
T075 [Analog In 2 Hi] Related Parameter(s): P035
, P038, T073, T074, T076, A152, A153
Stop drive before changing this parameter.
Sets the analog input level that corresponds to P035 [Maximum Freq].
Analog inversion can be accomplished by setting this value smaller than T074
[Analog In 2 Lo].
Values Default: 100.0%
Min/Max: 0.0/100.0%
Display: 0.1%
T076 [Analog In 2 Loss] Related Parameter(s): T055, T060, T065, T073, T074, T075
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 T074 [Analog In 2 Lo] to a minimum of 20% (i.e. 2 volts).
The drive will fault on an F29 Analog Input Loss
when the analog signal is lost if this parameter is used for the PID feedback, and this parameter and A152 [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): T078, T079, T080, T081, T090, T091
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.
T078 [Sleep Level] Related Parameter(s): T077, T079, T080, T081
Sets the analog input level the drive must reach to enter sleep mode.
Values Default: 10.0%
Min/Max: 0.0/100.0%
