Yaskawa Z1000 AC Drive HVAC - Manual (Page 219)

Settings for N.C. and N.O. input for the following functions were selected
simultaneously:
• External Search Command 1 and External Search Command 2 (61 vs. 62)
• Fast Stop N.O. and Fast Stop N.C. (15 vs. 17)
• KEB for Momentary Power Loss and High Slip Braking
(65, 66, 7A, 7B vs. 68)
• Motor Switch Command and Accel/Decel Time 2 (16 vs. 1A)
• KEB Command 1 and KEB Command 2 (65, 66 vs. 7A, 7B)
• FWD Run Command (or REV) and FWD/REV Run Command (2-wire)
(40, 41 vs. 42, 43)
• External DB Command and Drive Enable (60 vs. 6A)
• Motor Switch Command and Up 2/Down 2 Command (16 vs. 75, 76)
• Check if contradictory settings have simultaneously been assigned to the
multi-function input terminals.
• Correct setting errors.
One of the following settings was entered while H1- = 2 (External
Reference 1/2):
• b1-15 = 4 (Pulse Train Input) but the pulse train input selection is not set
for the frequency reference (H6-01 > 0)
• b1-15 or b1-16 set to 3 but no option card is connected
• Although b1-15 = 1 (Analog Input) and H3-02 or H3-10 are set to 0
(Frequency Bias)
Correct the settings for the multi-function input terminal parameters.
H2- is set to 38 (Drive Enabled) and H1- is not set to 6A (Drive
Enable).
Digital Operator Display Error Name
oPE04 Initialization Required, Term <–> Ctrl Chg
Cause Possible Solutions
The drive, control board, or terminal board have been replaced and the
parameter settings between the control board and the terminal board no
longer match.
Set A1-03 to 5550 to load the parameter settings stored in the terminal board
to the drive. Initialize parameters after drive replacement by setting A1-03
to 1110 or 2220.
Digital Operator Display Error Name
oPE05 Run Command/Frequency Reference Source Selection Error
Cause Possible Solutions
Frequency reference is assigned to an option card (b1-01 = 3) and an input
option card is not connected to the drive.
Reconnect the input option card to the drive.
The Run command is assigned to an option card (b1-02 = 3) and an input
option card is not connected to the drive.
Digital Operator Display Error Name
oPE07
Multi-Function Analog Input Selection Error
A contradictory setting is assigned to multi-function analog inputs H3-02,
H3-10, or H3-06 and PID functions conflict.
Cause Possible Solutions
At least two analog input terminals are set to the same function (i.e., at least
two of these parameters have the same setting: H3-02, H3-10, or H3-06).
Change the settings to H3-02, H3-10, and H3-06 so that functions no longer
conflict.
Note: Both 0 (Frequency Reference Bias) and F (Not Used) can be
set to H3-02, H3-10, or H3-06 simultaneously.
The following simultaneous contradictory settings:
• H3-02, H3-10, or H3-06 = B (PID Feedback) while H6-01
(Pulse Train Input) = 1 (PID Feedback)
• H3-02, H3-10, or H3-06 = C (PID Target Value) while H6-01 = 2
(pulse train input sets the PID target value)
• H3-02, H3-10, or H3-06 = C (PID Target Value) while b5-18 = 1
(enables b5-19 as the target PID value)
• H6-01 = 2 (PID target) while b5-18 = 1
(enables b5-19 as the target PID value)
Disable one of the PID selections.
