P2101[3] Stop reaction value
Min: 0 Def: 0 Max: 4
Level 3
Details:
Sets drive stop reaction values for fault selected by P2100 (alarm number stop reaction).
This indexed parameter specifies the special reaction to the faults/warnings defined in P2100 indices 0 to 2.
Enum:
0=No reaction, no display
1=OFF1 stop reaction
2=OFF2 stop reaction
3=OFF3 stop reaction
4=No reaction warning only
Note:
Settings 0 to 3 only are available for fault codes
Settings 0 and 4 only are available for warnings
Index 0 (P2101) refers to fault/warning in index 0 (P2100)
r2110[4] Warning number
Min: - Def: - Max: -
Level 2
Details
Displays warning information.
A maximum of two active warnings (indices 0 and 1) and 2 historical warnings (indices 2 and 3) may be viewed.
Index:
r2110[0] : Recent Warnings --, warning 1
r2110[1] : Recent Warnings --, warning 2
r2110[2] : Recent Warnings -1, warning 3
r2110[3] : Recent Warnings -1, warning 4
Note:
The keypad will flash while a warning is active. The LEDs indicate the warning status in this case.
If an AOP is in use, the display will show number and text of the active warning.
Indices 0 and 1 are not stored.
P2111 Total number of warnings
Min: 0 Def: 0 Max: 4
Level 3
Details:
Displays number of warning (up to 4) since last reset. Set to 0 to reset the warning history.
r2114[2] Run time counter
Min: - Def: - Max: -
Level 3
Details:
Displays run time counter. See P-948 (fault time).
P2115[3] AOP real time clock
Min: 0 Def: 0 Max: 65535
Level 3
Details:
Displays run time counter. See P-948 (fault time).
P2181 Belt failure detection mode
Min: 0 Def: 0 Max: 6
Level 2
Details:
Sets belt failure detection mode. This function allows detection of mechanical failure of the drive train, for example, a
broken drive belt. It can also detect conditions which cause an overload, such as a jam.
Two methods are provided of detecting the failure.
The fist is achieved by comparing the actual frequency/torque curve with a programmed envelope (see P2182-P2190). If
the curve falls outside the envelope, a warning or trip is generated.
The second uses a pulse train from a simple sensor on the driven machine connected to the encoder circuit within the drive
ASIC via a digital input. The pulse train, normally detecting one pulse per revolution of the drive machine, is converted to a
frequency reference and compared with the actual inverter output frequency.
Enum:
0=Belt failure detection disabled
1=Warn low torque/speed
2=Warn high torque/speed
3=Warn high/low torque/speed
4=Trip low torque/speed
5=Trip high torque/speed
6=Trip high/low torque/speed
P2182 Belt threshold frequency 1
Min: 0.00 Def: 5.00 Max: 650.00
Level 3
Details:
Sets a frequency threshold F1 for comparing actual torque to torque the envelope for belt failure detection.
The frequency torque envelope is defined by 9 parameters-3 are frequency parameters (P2182-P2184), and the other 6
define the low and high torque limits (P2185-P2190) for each frequency.
Note:
The torque is unlimited below P2182, and above P2184. Normally P2182 <= lower torque limit (P1521), and P2184
>=upper torque limit (P1520).
P2183 Belt threshold frequency 2
Min: 0.00 Def: 30.00 Max: 650.00
Level 2
Details:
Sets a threshold F2 for comparing actual torque to torque the envelope for belt failure detection.
Note:
See P2182 (belt threshold frequency 1).
P2184 Belt threshold frequency 3
Min: 0.00 Def: 50.00 Max: 650.00
Level 2
Details:
Sets a threshold F3 for comparing actual torque to torque the envelope for belt failure detection.
Note:
See P2182 (belt threshold frequency 1).
