Terminal
Description
Vmet
Analog output 1, which is a dedicated voltage output.
The default signal range is from 0 to 10 Vdc (5 mA maximum). It is proportional to the variable
configured by parameter
700 (Vmet Config)
. It may be calibrated while the drive
701 (Vmet Span)
(see page 91)
.
Imet
Analog output 2, which is a dedicated current output.
The default signal ranges from 0 to 20 mAdc (50 to 500
Ω
). It is proportional to the variable
702 (Imet Config)
.It may be calibrated while the drive is
704 (Imet Offset)
and
see page 92)
.
Vin1
Analog Input 1, which is used to provide speed references.
The default input signal is 0 to 10 Vdc (the type of input signal is selected with parameter
205
(Vin1 Config)
;
). Parameters
may be used to
offset the starting value of the range and the size of the range, respectively;
see page 77
for
more information.
If a 0 to 20 mAdc input signal is configured, the burden is 250
Ω
. If a 0 to 10 Vdc input signal is
configured, the input impedance is 475 k
Ω
.
A potentiometer with a range of 1 to 10 k
Ω
is suggested for this input.
+10
This terminal is a +10 Vdc source for customer-supplied potentiometers. The maximum load on
this supply cannot exceed 10 mAdc.
Cin+ / Cin-
Current Input.
The default input signal is 4-20 mA, although this range may be adjusted by using parameters
(which configures an offset for the range) and
(to reduce or
enlarge the range — for example, setting this parameter to 50% results in a range of 4-12 mA).
See page 77
for more information on these parameters.
The burden for this terminal is 50
Ω
.
Vin2
Voltage Input 2, which is used to provide speed references.
The default input signal is 0 to 10 Vdc (the type of input signal is selected with parameter
211
(Vin2 Config)
;
. Parameters
may be used to
offset the starting value of the range and the size of the range, respectively;
see page 78
for
more information.
A potentiometer with a range of 1 to 10 k
Ω
is suggested for this input.
Acom
Common for the Analog Inputs and Outputs. Note that while there are three Acom (common)
terminals, they connect to the same electrical point.
+24
A source for positive nominal 24 Vdc voltage, and has a source capacity of 150 mA.
FWD
Forward Direction Selection terminal. This may be connected for two-wire maintained or three-
wire momentary operation.
REV
Reverse Direction Selection Terminal. This may be connected for two-wire maintained or three-
wire momentary operation.
R/J
Run/Jog Selector. When this terminal is connected to +24 or common (depending upon Active
Logic setting), momentarily connecting either FWD or REV to +24 results in a latched run mode
(3-wire operation).
MOL
Motor Overload input terminal. This requires a N/O or N/C contact for operation, referenced to
+24 or COM, depending on Active Logic setting.
