10.6 SPEED REFERENCE SELECTION
If an analog speed reference input is used to control the drive speed, terminal TB-13A, 13B,
or 13C (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-2, 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 13C,
speed control will default to STANDARD mode, which is governed by the setting of Parameter 05 -
STANDARD SPEED SOURCE. 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-13C 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, TB-13B to select PRESET SPEED #2, and
TB-13C to select PRESET SPEED #3. There are a total of seven preset speeds, which are
activated by different combinations of contact closures between TB-13A, 13B, 13C and TB-2. Refer to
Parameters 31-37 in Section 15.0 - DESCRIPTION OF PARAMETERS.
JOG
TB-13B can be programmed to select either JOG FORWARD or JOG REVERSE. The Jog speed is set
by PRESET SPEED #2. Close TB-13B to TB-2 to JOG, and open the contact to STOP.
When operating in JOG mode, the STOP terminal (TB-1) and the STOP key (on the
optional remote keypad) 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-13C 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-13C for INCREASE
FREQ (05). Closing TB-13B to TB-2 will cause the speed setpoint to decrease until the contact is
opened. Closing TB-13C to TB-2 will cause the speed setpoint to increase until the contact is opened.
The INCREASE FREQ function will only operate while the drive is running.
