CTB1-10 through CTB1-12 Provides customer with a drive fault status via contact closure. Contacts are
rated 5A @ 240V AC, 24V DC.
CTB1-13 through CTB1-15 Provides customer with a drive running status via contact closure. Contacts are
rated 120/208 VAC or 30 VDC, 5 A.
CTB1-25 through CTB1-26 Place normally open contacts between CTB1-25 and CTB1-26. Closure
between these contacts cause the motor to run at a preset speed (speed
programmed by function code C20) or from the AC input power. The preset
speed command is issued if the Drive/Off/Bypass and Test/Isolate/Normal
selector switches are in “Drive” and “Normal” mode of operation, regardless of
the H-O-A switch position. If the Drive/Off/Bypass selector switch is the “Off”
position the motor will not run. A typical use for this input is a smoke purge
command.
CTB1-8 through CTB1-9 These positions come with a jumper from the factory to allow testing of the
drive with the Test/Isolate/Normal selector switch. When the
Test/Isolate/Normal switch is placed in the “Test” position, AC input power will
be applied to the drive and it will run at a speed determined by the speed pot or
the “Auto” speed reference, depending on the position of the H-O-A switch.
However, some inverter function codes can not be changed with a run
command issued to the drive. Therefore removal of this jumper and the
Test/Isolate/Normal switch in the “Test” mode allows all function codes to be
accessible.
CTB1-20 through CTB1-22 Connect customer supplied 0-10 VDC or 4-20 mA “Auto” speed reference signal.
This signal functions as the drive’s speed reference when the H-O-A switch is in
the “Auto” position. If utilizing a 0-10 VDC signal, CTB1-20 and CTB1-22 are to
be used. If utilizing a 4-20 mA signal, CTB1-20 and CTB1-21 are to be used.
CTB1-20 is the common terminal for either input signal. See the customer
interface diagram for details.
CTB1-31 through CTB1-32 These positions come with a jumper from the factory. Put normally open enable
contacts between CTB1-31 and CTB1-32.
Closure between the contacts is required for the motor to run in either drive or
Bypass mode.
CTB1-33 through CTB1-34 Smoke Purge circuit
CTB1-27 through CTB1-28 Analog output 0/4 – 20mA.

CAUTION: Jumpering CTB1-35 and CTB1-36 together will not allow for motor
flux to decay prior to applying AC line power to the motor in the event of a drive
fault. The absence of the 10-second time delay can result in a devastating
torque pulse which can damage your motor, driven load and/or installation. The
AF 600 FP & Bypass panel does not have a line synchronizing function to
permit a smooth switchover to AC line power, therefore a time delay is the only
way to ensure a safe transition.
NOTE: 4-20 mA output signal will be available from the drive at
terminal 39 and 42, which is wired for customer to terminal board
CTB1-27 and CTB1-28.
