Stop and position hold control (IN A and IN B)
If the same control signal is applied at both inputs (either both inputs are set to 0 or
both inputs are set to 1), the enabled motor decelerates to speed 0 with the parame-
terized deceleration ramp. After reaching speed 0, the drive remains in position hold
control
(KP_H >
0) or the output stage is disabled
(KP_H =
0). This depends on the
parameterization selected. In the case of position hold control, the drive continues to
be supplied with current and also thermally loaded in an idle state. When the output
stage is disabled, there is no current supply and the drive can be moved via external
torque. For drives with optional holding brake, the brake is applied when the output
stage is disabled and thus acts against the external torque.
Speed setpoints (IN 1 and IN 2 on Pin 3 and Pin 4)
The user is provided with 4 different fixed setpoints for open-loop speed control. Con-
trol takes place via 2 binary coded inputs. If control signals are not applied
(IN 1 =
0
and
IN 2 =
0), a selection is made between the fixed setpoint N4 or an analog setpoint
0 –
10
V. This depends on the parameter setting. If parameter N4 has a value greater
than 0
(N4 >
0), this value has priority. If parameter
N4 =
0, the voltage value at the
analog input
(pin
8 and
pin
9) determines the speed setpoint. If N4 is parameterized to
0 and no analog signal is present, the speed setpoint 0 applies.
