10 .5 SPEED/TORQUE REFERENCE SIGNALS
SPEED POT Connect the wiper of the speed pot to terminal TB-5, and the
high and low leads to terminals TB-6 and TB-2, respectively .
The speed pot can be 2 .5kΩ up to 10kΩ .
0-10 VDC Wire the positive to terminal TB-5 and the negative to
terminal TB-2 . TB-5 input impedance is 120 kΩ .
-10 to +10 VDC Connect the signal wire to TB-5 and the common to TB-2 .
TB-5 input impedance is 120 kΩ . This signal can be used for
speed reference only .
4-20 mA Wire the positive to terminal TB-25 and the negative to
terminal TB-2 . TB-25 input impedance is 100Ω .
10 .6 SPEED REFERENCE SELECTION
If an analog speed/torque reference input is used to control the drive, terminal TB-13A, 13B,
13C, or 13D (Parameter 10, 11, 12, or 49) may be programmed as the input select for the
desired analog input signal . When that TB-13 terminal is then closed to TB-4, the drive will
respond to the selected analog reference input .
If an analog speed/torque reference input is not selected on the terminal strip using TB-13A,
13B, 13C, or 13D, control will default to STANDARD mode, which is governed by the setting
of Parameter 05 - STANDARD REFERENCE SOURCE . The STANDARD REFERENCE
SOURCE can be the s and t buttons on the front of the drive, PRESET SPEED #1 (speed
mode only; not torque mode), a 0-10 VDC signal, or a 4-20 mA signal .
0-10 VDC, -10 to +10 VDC, and 4-20 mA INPUT SIGNALS
TB-13A, TB-13B, TB-13C, and TB-13D can all be programmed to select a 0-10 VDC
or 4-20 mA analog speed/torque reference input . To select a -10 to +10 VDC bipolar
speed input, Parameter 07 - BIPOLAR REFERENCE SELECTION must be set to
ENABLE (02), which disables all other speed references except for JOG FORWARD
and JOG REVERSE (refer to Parameter 07) .
PRESET SPEEDS
TB-13A (or 13D) 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 (or 13D), 13B, 13C and TB-4 . Refer to Parameters 31-37 in
Section 15 - DESCRIPTION OF PARAMETERS .
JOG (not available in Vector Torque mode)
TB-13B can be programmed for JOG FORWARD, and TB-13C can be programmed
for JOG REVERSE . The JOG FORWARD speed is set by PRESET SPEED #2, and
the JOG REVERSE speed is set by PRESET SPEED #4 . Close TB-13B or TB-13C to
TB-4 to JOG in the desired direction, and open the contact to STOP .
