7000 “A” Frame 7000A-RM001A-EN-P – January 2011
It is necessary to activate each status indicator used by the customer
to ensure that they have connected their control to the drive
correctly. This can be achieved by changing the drive status (ready,
faulted, warning etc.).
Analog I/O
It is possible to configure all of the drive’s analog inputs and outputs
without running the motor. The following information describes how
to set up the following drive features:
• Analog Inputs
– Analog Reference Command Input Scaling (Local, Remote)
– Minimum Setting
– Maximum Setting
– Digital Reference Command Input Scaling (Digital)
• Analog Outputs
All of the Analog I/O connections are made on the ACB.
Analog Inputs
• Analog Command Input Scaling
– Prior to commencing the reference command input scaling it
is necessary to ensure that the reference command input
selection has been configured as desired. This requires
setting Reference Select [P7] to the appropriate input source.
– Set the utilized Reference Command minimum (SpdCmd
Pot(L), SpdCmd Anlg Inp(R) and SpdCmd DPI ( D) to the
desired value. The minimum reference command input
setting on a drive without a tachometer is 6 Hz. Without
tachometer control, do not set the reference command
minimum parameter below 6 Hz. A control with tachometer
feedback will allow a minimum speed of 1 Hz. With
tachometer control, do not set the reference command
minimum parameter below 1 Hz.
– Set the utilized Reference command (L, R and D) Maximum
parameters so that with full reference command inputs, the
associated Reference command Variables read the desired
maximum value.
– The various reference command maximums usually have to
be increased above the desired maximum value to
compensate for the loading down of their 10 volt input rails
by the attached potentiometer or isolator.
