10.6 Speed Reference Selection
If an analog speed reference input is used to control the drive speed, terminal TB-13A,
13B, or 13E (Parameter 10, 11, or 12) may be programmed as the input select for the
desired analog input signal. When that TB-13 terminal is then closed to TB-11, the drive
will follow the selected analog speed reference input.
If an analog speed reference input is not selected on the terminal strip using TB-13A, 13B,
or 13E, speed control will default to STANDARD mode, which is governed by the setting
of STANDARD SPEED SOURCE (Parameter 05). The STANDARD SPEED SOURCE
can be the and buttons on the front of the drive, PRESET SPEED #1 (Parameter
31), a 0-10 VDC signal, or a 4-20 mA signal.
0 - 10 VDC and 4 - 20 mA INPUT SIGNALS
TB-13A, TB-13B, and TB-13E can all be programmed to select a 0-10 VDC or 4-20 mA
analog speed reference input.
PRESET SPEEDS
TB-13A can be programmed to select PRESET SPEED #1 (04), TB-13B to select
PRESET SPEED #2 (04), and TB-13E to select PRESET SPEED #3 (04). There are a
total of seven preset speeds, which are activated by different combinations of contact
closures between TB-13A, 13B, 13E and TB-11. Refer to Parameters 31-37 in Section
15, DESCRIPTION OF PARAMETERS.
JOG
TB-13B can be programmed to select either JOG FORWARD (07) or JOG REVERSE
(08). The Jog speed is set by PRESET SPEED #2 (Parameter 32). Close TB-13B to
TB-11 to JOG, and open the contact to STOP.
WARNING!
When operating in JOG mode, the STOP signal and the AUXILIARY STOP function
(see Parameters 10-12) WILL NOT stop the drive. To stop the drive, remove the
JOG command.
JOG REVERSE will operate the drive in reverse rotation even if ROTATION
DIRECTION (Parameter 17) is set to FORWARD ONLY.
NOTE
If the drive is commanded to JOG while running, the drive will enter JOG mode
and run at PRESET SPEED #2. When the JOG command is removed, the drive
will STOP.
MOTOR OPERATED POT (MOP) / FLOATING POINT CONTROL
TB-13B and TB-13E are used for this function, which controls the drive speed using
contacts wired to the terminal strip. Program TB-13B for DECREASE FREQ (05), and
program TB-13E for INCREASE FREQ (05). Closing TB-13B to TB-11 will cause the
speed setpoint to decrease until the contact is opened. Closing TB-13E to TB-11 will
cause the speed setpoint to increase until the contact is opened. The INCREASE FREQ
function will only operate while the drive is running.
