Speed Reference Selection - Lenze SM004S Operating Instructions Manual

3.5.6

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 p and q 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 4.4, 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.
