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.

When selected, if a speed, which can be parameterized, is exceeded, the 2nd
torque limit is activated.
Generates an internal frequency setpoint with adjustable frequency and speed.
Acknowledges a fault/error message after the cause has been removed.
Note: Terminal 65 (controller enable) must be open.
When selected, a changeover is made from ramp–up/ramp–down time 1 to
ramp–up/ramp–down time 2. The ramp–up/ramp–down times 1 and 2 can be
separately entered for each of the maximum of four motor data sets.
Specifies the motor direction of rotation
Terminal open: Clockwise phase sequence
Terminal energized: Counter–clockwise rotating field
Note: Positive analog setpoint, 0 ... 10 V
Motorized potentiometer function. Starting from an initial value which can be
parameterized, the speed setpoint can be continuously adjusted using these
two select terminals.
If the enable voltage is connected to this terminal, the ramp–function generator
is bypassed.
Via this terminal, the integral component of the PI speed controller can be
inhibited (I component=0ms).
A total of four different motor data sets can be selected using these terminals.
Each data set is assigned the following parameters: Motor data, setpoint
normalization, ramp–function generator, controller parameters, current and
power limiting and frequency bandstop filter.
A total of 8 parameter sets for speed monitoring, torque limiting and torque
monitoring can be entered using these terminals.
Terminal open–circuit: Digital zero setpoint
Terminal selected: Setpoint enabled (analog setpoint or speed setpoint)
A maximum of 16 speed setpoints can be selected. Setpoint 1 corresponds to
the standard setpoint (analog setpoint and the internal setpoint); setpoints 2 to
16 are fixed setpoints which can be parameterized.
