ATTENTION: Signal common is internally connected to chassis
ground. User minus or user common connections to signal common
must be capable of accepting this. If earth ground or cable shields
are used as signal current paths, signals may be degraded. Terminal Block TB2 -
Control and Signal Wiring (cont.)
Terminal 5 and Signal Common
0-10V DC Input
This terminal is provided to terminate a 0 to +10V DC speed reference
signal. Parameter 84 sets the 0-10V DC signal to be either directly or
inversely proportional. The minus signal is terminated at Terminals 3 or 4.
The input impedance from Terminal 5 to either 3 or 4 is approximately
100k
Ω
. The range of frequency control is between the minimum and
maximum drive frequency settings. The frequency resolution is the range
divided by 976 (but no less than 0.005Hz). Refer to the 1336 Programming
Manual for details.
!
ATTENTION: Unexpected machine acceleration can cause injury
or death.
If Parameter 84 is enabled, a loss of the 0-10V DC reference signal
at drive terminal block TB2 will allow the drive to immediately
accelerate to the maximum frequency set by Parameter 19.
Ensure that all control connection integrity is maintained and
routinely inspected.
!
ATTENTION: Terminal 5 of TB2 is internally protected from
reverse polarity signals or input signals rising above 12V DC. If
reverse polarity or voltage levels are maintained above 12V DC,
signals may be degraded and component damage may result.
