25-FEXT1 - External Speed #1
Hz
L3
26-FEXT2 - External Speed #2
Both 25-FEXT1 and 26-FEXT2 are RAM parameters that allow the host computer to write real values for
output frequency in storage registers. Parameter 24-FSEL then can be used to have the inverter to look at
these values as the active speed reference. The range is 0.00 to 400 Hz.
28-TLEXT - External Torque Limit Reference
L3
Like 25-FEXT1 and 26-FEXT2, 28-TLEXT is a RAM parameter that works as a storage register. Real
number values between 0 and 150% or drive rating can be stored here. Based on the value of 27-TLSEL,
28-TLEXT can become the active torque limit reference.
29-COUT - Control Output Status
L3
The binary word that is represented by this integer value can be used to deduce the status of the drive's
digital outputs. Bits 5 thru 7 are not used and will always be "0". If bits 4 thru 0 are active, the representation
is as follows:

23-CNTL - Control Information Byte
L3
This RAM parameter is the mechanism thru which actual SIO control of the inverter is achieved. It is
represented by a binary word. The activation of each binary bit is read by the inverter as if the respective
terminal were activated at the terminal strip. The breakdown is as follows:
BIT #
FUNCTIONAL RESPONSE
7
A reverse command is initiated as though the REV terminal is activated from the terminal strip.
6
A forward command is initiated as though the FWD terminal is activated from the terminal strip.
5
Once this command is initiated, either directional command will be maintained until the inverter is
commanded to stop or change direction, just as if the R/J terminal were activated.
4
Activating this bit will put the inverter in a coast to stop mode.
3
Activating this bit is functionally the same as engaging the ART terminal.
2
Activating this bit is functionally the same as engaging terminal PS3.
1
Activating this bit is functionally the same as engaging terminal PS2.
0
Activating this bit is functionally the same as engaging terminal PS1.
BIT #
FUNCTIONAL INDICATION
4
Will indicate the activity of ST5, used only on option boards.
3
Will indicate the activity of STR, the auxiliary relay mounted on the control board.
2
Will indicate the activity of ST3, one of the open collector outputs on the control board, or the
option card mounted relay following its active state.
1
Will indicate the activity of ST2, one of the open collector outputs on the control board, or the
option card mounted relay following its active state.
0
Will indicate the activity of ST1, one of the open collector outputs on the control board, or the
option card mounted relay following its active state.
