The control - imputs of the drive are protection - isolated ( in accordance with VDE 0884 ). The drives are also
protected against a direct short between motor - lines or between motor - line and earth.
The electronic limiter of the motor - current allows at case - temperatures below 30°C a maximum motor -
power of appr. 150 % of nominal power. At higher temperatures the maximum power is reduced to appr.
120 % of nominal power at 80°C case - temperature. The thermal - protection is switching off the drive at appr.
85°C. The reset of the thermal switch off must be done by switch off the mains for at least 10 sec.
To control the drive signals from potentiometer, ext. voltage 0...10V, ext. current 0...20 mA or 4...20 mA are
possible. The adaption of the input - circuit to correspond to the control - signal is made by the jumper B1
and B2.
Attention! If the input - circuit is set for control from a potentiometer or with 0...10 V, a disconnection of the
control - input ( terminal 2 ) causes a control signal of half the adjusted maximum! Open control - input is
therefore to be avoided.
To enable the drive a closed loop must be connected to the enable - input.
Control - lines with a length of more than 2 meters must be shielded. The shield should be connected to
terminal 4. Below the length of 2 meters shielding is recommanded if a high disturbance - level is present in the
surrounding.
