5.4.1 Select terminal functions
The select input terminals E1 to E9 (max. 9) are freely–programmable. A control
parameter is assigned to each select terminal, in which the code number of the
selected function is entered.
Table 5-10 Select terminal functions
Select terminal Function
2nd torque limit value When selected, if a speed, which can be parameterized, is exceeded, the 2nd
torque limit is activated when a speed, which is parameterized, is exceeded.
Oscillation 2 internal speed setpoints, where the frequency and speed can be adjusted, are
generated.
Reset fault memory (reset) 1) Acknowledges a fault/error message after the cause has been removed.
Note: Terminal 65 (controller enable) must be open.
Open–loop torque controlled
operation 1)
The analog setpoint is interpreted as torque setpoint in this mode. (This function
is required for master–slave drives)
Open–loop torque controlled
operation with slip monitoring
Open–loop torque controlled operation with slip monitoring
Star–delta operation When the signal changes, the motor data sets are also changed and a change-
over made from the star to the delta winding configuration using control
commands. Note: This function can only be used for motors with star/delta
windings.
M19 operation NC auxiliary function for oriented spindle stop. When selected, and if a speed,
which can be parameterized, is fallen below, a finer speed setpoint normalization
is selected.
Ramp–time = 0 If the enable voltage is connected to this terminal, the ramp–function generator
is bypassed.
Integrator inhibit, speed
controller 1)
The integral component of the PI speed controller is inhibited using this terminal.
Gearbox stage (max. 3 terminals) A total of 8 parameter sets for setpoint normalization, speed monitoring, con-
troller setting, torque limiting and torque monitoring can be entered using these
terminals.
Setpoint enable Terminal open–circuit: Digital zero setpoint
Terminal selected: The setpoint is enabled (analog setpoint or oscillation setpoint)
Positioning on When selected, the internal closed–loop position control is selected and the
spindle is moved into the required position.
Position reference value 1–4
(max. 2 terminals)
Using these terminals, a total of 4 parameterizable position reference values can
be entered.
Incremental positioning When selected, the spindle moves from the actual position–controlled position
through a specified position difference.
Spindle re–synchronization The spindle is re–referenced: This is necessary after every mechanical gearbox
stage changeover.
C axis Changeover to a finer C–axis setpoint normalization.
Note: Only setpoint input 2 (terminal 24–8) is evaluated.
HPC axis 1) Changeover to High Precision C axis mode; i.e. finer setpoint normalization and
higher speed control loop dynamic performance with a lower functional scope
(only E1 to E6 are evaluated).
Note: Only setpoint input 2 (terminal 24–8) is evaluated.
Speed setpoint smoothing 1) The speed setpoint smoothing is activated with a time constant, which can be
parameterized.
Suppress fault 11 1) Fault message 11 is suppressed (speed controller at its limit) for the function
”travel to endstop”.
Inverter clock frequency
changeover 1)
It is possible to select different inverter clock frequencies using the select
terminals.
1) Only these terminal functions are available in the HPC axis mode.
