Message Definition
Err2 Err2 Var02 _PPR * Var03 _PULSE_
MAX_RPM combo is less than
0.5Hz
(when
Var01 = 0001 for
Pulse-Train Encoder Type).
Err2 Err2 Var03 _RPM_at_20mA = 0000
(when Var01 = 0000 4-20mA
Encoder Type).

_PPR *

_PULSE_
MAX_RPM combo exceeds
9999Hz
(when
Var01
= 0001 for
Pulse-Train Encoder Type only).
Err5 Err5 A Speed Relay_Setpt exceeds
9999Hz
(when
Var01
= 0001 for
Pulse-Train Encoder Type).
Err5 Err5 Either a a speed relay setpt is
grossly large, or
Var10 _MAX_
ANALOG_RPM is grossly larger
than
Var03 _RPM_at_20mA,
either way causes the Speed
Relay_Setpts to exceed an
equivalent 9999Hz
(when
Var01 = 0000 for 4-20mA
Encoder Type).

Err3 Err3 Speed signal is above 9999Hz
(when
Var01 = 0001 for
Pulse-Train Encoder Type only).
Err4 Err4 Speed signal is greater than the
maximum allowed for the present
Var02 _PPR value and Var03 _
PULSE_MAX_RPM value
(when
Var01 = 0001 for
Pulse-Train Encoder Type only).
Also, when the speed signal is from an Analog Encoder,
these following 4-20 mA sensor ‘out-of-range’ operational
error messages can be seen on the 4-digit LED speed display.
(Because only one of these four 4-20 mA sensor operational
error messages can happen at a given time, they each have
equal ranking against each other in the ‘out-of-range’ group
of messages):

capability of the displays.
Stop 0000 Speed signal is 0 Hz, 0 RPM, 0%,
or 4mA.
To summarize, the hardware error message of “Err6” is
highest priority of all messages.
The speed calibration errors of ‘Err2’, ‘Err1’, ‘Err5’ are next
highest priority, followed by the speed operational errors of
‘Err3’ and ‘Err4’.
Next in priority are all of the 4-20 mA sensor out-of-range
operational errors of CLS, HI, LO, and OPn.
Finally, at the bottom of the priority list is ‘FFFF’ and
‘0000’. The ‘HI’ and ‘CLS’ analog 4-20 mA input sensor
operational errors, take precedence over the ‘FFFF’ 4-digit
LED overflow output error. This because you can’t have valid
output results unless of course you first have proper input
data. Because of this the ‘HI’ and ‘CLS’ analog input errors
outrank the ‘FFFF’ display output error.
The ‘LO’ and ‘OPn’ analog 4-20 mA input sensor
operational errors, take precedence over the ‘0000’ 4-digit
zero speed value. Again, this since you can’t have valid
output results unless of course you first have proper input
data. Because of this the ‘LO’ and ‘OPn’ analog input errors
outrank the ‘0000’ display zero speed value.
Note: These ‘out-of-range’ error messages involved with the
4-20 mA speed sensor, can also be seen in the 3-digit
