1.10 OPTIONAL THINGS

Encoder verification: Set the Drive in V/f mode and
run the motor, enable and start the drive and set an
analog reference. If the reference is positive on
terminal 1 with respect to 2 (common) the motor
should be turning clockwise. With the motor turning
clockwise (looking at the driving shaft pointing at
you.) (you can even do this by hand while not
enabled), monitor the encoder measurement by
clicking "Monitor/measurements/speed/speed in rpm/
Enc 1 speed". The speed should be positive, not
negative. If it is negative, then A and A- or B and B-
should be interchanged on the encoder. Now return
to the "Set Up for Running" section.
Current Limit: The current limit will have been set
to approximately 136% by default in the previous setup
(exact number is a function of the power factor but the
difference is very small). The value actually set can
be verified by (from "Basic Menu") pressing down/
right arrow to "Limits", then [Enter], then down/right
arrow to "current limits", then [Enter], then down right
arrow to "T current lim" and [Enter]. The value of T
current limit can be changed if you like to a higher (or
lower) number. Bear in mind that the ultimate limits
are based on the capacity of the drive, not the motor.
T current is the torque producing component of total
current. Settings in excess of 200% are possible,
although the motor may not be able to handle this
current. Most motors are rated only for 150% for 1
minute. The drive will protect itself though an
intelligent temperature, voltage, I
regardless of how you set this number. The drive will
provide 150% of the value in "Configuration/Full Load
Current" for 1 minute (200 % for a short time).
I/O Configuration: This drive can be configured in
virtually any imaginable way.
The standard drive has three standard analog inputs
and gives you two analog outputs as well as six digital
inputs and two digital outputs which are assignable
and configurable. The drive is defaulted already
to provide the analog outputs as Actual speed and
load (Torque current), but may require some scaling.
To set up the drive for two analog outputs (one for
speed and one for load) for metering or other
purposes, do the following:
Refer to the "Control terminals" section of this
guide showing a description of the connection of
the regulation section and how to make them. A
more detailed description and discussion of the I/
O are showed in the manual. The analog outputs
are defaulted to a scale of 1, which means 10 volts
out at max parameter value. In other words, if
QS

analog output 1 is set to maximum speed then max
speed will be scaled 10 Vdc (maximum output
voltage available) at "Speed Base Value" (found
under Configuration). If you wanted 5 volts out at
max speed then set the scale to 0.5. If the output
was set to Torque current (the torque producing
current, which is the part of the total motor current
that actually produces torque), then 10 Vdc would
be rated current. If you wanted the output to be
10 Vdc at 150% of "Full Load Current" (found
under Configuration) then the scale would be 0.66.
The standard factory default is already set up to
put out speed (with scale factor of 1) on analog
output 1 (terminals 21 and 22) and load (Torque
current, with scale factor of 1) on analog output 2
(terminals 23 and 22). Note that terminal 22 is a
common for both the outputs. This common can
be grounded, and should be grounded somewhere,
preferably at the load device (meter).
How to disable analog input 1 as ramp reference:
(Analog inputs 2 and 3 are already off from default,
#1 is defaulted to Ramp ref 1). This is being done
now to allow us to use the keypad to set speed in
digital way.
· Press [Up arrow]/[Down arrow] to "I/O
Config", then [Enter].
· Press [Down arrow] to "Analog inputs", then
[Enter] for Analog input 1, then [Enter] to Select
input 1, then [Enter] to display the setting, which
T algorithm
2
will be "Ramp ref 1".
· Press [Up arrow] / [Down arrow] keys until
"OFF" is displayed, then [Enter].
How to enable analog input 2 as ramp reference
· Press [Up arrow]/[Down arrow] to "I/O
Config" and press [Enter], then down right arrow
to "Analog inputs" then [Enter] for "Analog
input 1" then [Down arrow] to "analog input 2
then [Enter] to "select input 2", then [Enter]
again to see the set up. It says "OFF". Use the
[Up arrow] / [Down arrow] keys to display
"Ramp ref 1" (if this setting is not already used,
or "Ramp ref 2") and [Enter]. This means the
Analog input 2 (terminals 3 and 4) will be the
ramped (accel/decel) speed reference for the
drive.
The AVy manual on CD-ROM shows the entire con-
figuration of the I/O and other set up for the drive. It
this does not help, call the customer service and we
can help you with your specific configuration.
