is not set in parameter o4-17 and a feature
that requires RTC information is enabled.
• The drive is a new drive, first power-up
condition
• o4-17 was set to 2, Reset, by the user,
manually clearing the Real-Time Clock
data.

TLGI Geothermal Input
Cause
The input signal level has dropped below
3 mA or risen above 21 mA when the drive
was running and b1-01 = 5, H3-0o = 21
(Geothermal Input), H3-0o = 2
(4 to 20 mA), and Q2-09 = 2 (Fault).
The drive was running while b1-01 = 5,
H3-0o≠ 21 (Geothermal Temp), and
Q2-09 = 2 (Fault).

Time Not Set
Possible Solution
Set o4-17 to 1 to set the time for the HOA keypad.
The drive will display the "Clock Not Set" alarm when the Real time Clock is not set. Additionally, at power
up, if the "TIM" condition is present, the drive will automatically switch to the time setting screen (o4-17 =
1) for 30 seconds to prompt the user to set the Real-Time Clock.
Cycle power to the drive and set the Real Time Clock within 30 seconds of power-up, or set the clock
manually via parameter o4-17.
Replace the HOA keypad battery and set the Real-Time Clock.
Replace the digital operator. For instructions on replacing the HOA keypad, contact Yaskawa or your nearest
sales representative.

The current has fallen below the minimum value set for torque detection (L6-02) for longer than the allowable
time (L6-03).
Check the settings of parameters L6-02 and L6-03.
Check the load for any problems.
Undertorque Detection 2
The current has fallen below the minimum value set for torque detection (L6-05) for longer than the allowable
time (L6-06).
Check L6-05 and L6-06 settings
Check the load for any problems.
