PRODUCT
Observe the warning labels on the product!
ICON DESCRIPTION
Electrostatic sensitive devices
Before working on the drive, the staff must ensure to be free of electrostatic charge!
Dangerous electrical voltage
Before working on the drive, check whether all power connections are dead! After mains OFF, power connections X100 and X105 carry a dangerous electrical

Use personal protective equipment or wait until devices have cooled down!
MOTOR
If there is a short circuit of two power transistors, a residual movement of up to 180°/number of pole pairs can occur at the motor! (For 4-pole motor: residual movement max. 180°/2 = 90°).
This residual movement must be taken into consideration by the user for his/her risk assessment.
1.2 INTENDED USE
The product:
– must only be actuated under the operating conditions prescribed in this documentation.
– meets the protection requirements of 2014/35/EU: Low-Voltage Directive.

3.6 CONNECTION OF THE SAFETY MODULE
3.6.1 Important notes
DANGER!
Improper installation of the safety engineering system can cause an uncontrolled starting action of the drives.
Possible consequences: death or severe injuries.
– Safety engineering systems may only be installed and commissioned by qualified and skilled personnel.
– All control components (switches, relays, PLC, ...) and the control cabinet must comply with the requirements of the EN ISO 13849-1 and the EN ISO 13849-2.
– Switches, relays with at least IP54 enclosure.
– Control cabinet with at least IP54 enclosure.
– It is essential to use insulated wire end ferrules for wiring.
– All safety relevant cables outside the control cabinet must be protected, e.g. by means of a cable duct.
– Ensure that no short circuits can occur according to the specifications of the EN ISO 13849-2.
– All further requirements and measures can be obtained from the EN ISO 13849−1 and the EN ISO 13849-2.
– If an external force acts upon the drive axes, additional brakes are required. Please observe that hanging loads are subject to the force of gravity!
– The user has to ensure that the drive will only be used in its intended application within the specified environmental conditions. This is the only way to comply with the declared safety-related
characteristics.
DANGER!
With the "Safe torque off" (STO) function, no "emergency stop" in terms ‑EN 60204-1 can be executed without additional measures. There is no isolation between the motor and drive, no service
switch or maintenance switch!
Possible consequence: death or severe injuries.
– "Emergency stop" requires electrical isolation, e.g. by a central mains contactor.
DANGER!
Automatic restart if the request of the safety function is deactivated. Possible consequences: death or severe injuries.
– You must provide external measures according to EN ISO 13849−1 which ensure that the drive only restarts after a confirmation.
NOTICE!
Overvoltage.
Destruction of the safety component.
– The maximum voltage (maximum rated) at the safety inputs is 32 V DC. The user must make provisions to avoid that this voltage is exceeded.

4 COMMISSIONING
4.1 IMPORTANT NOTES
Incorrect settings during commissioning may cause unexpected and dangerous motor and system movements.
Possible consequence: death, severe injuries or damage to material assets.
– Clear hazardous area.
– Observe safety instructions and safety clearances.
4.2 BEFORE INITIAL SWITCH-ON
Prevent injury to persons and damage to material assets. Check the following before switching on the mains voltage:
– Is the wiring complete and correct?
– Are there no short circuits and earth faults?
– Is the motor circuit configuration (star/delta) adapted to the output voltage of the drive?
– Is the motor connected in-phase (direction of rotation)?
– Does the "emergency stop" function of the entire plant operate correctly?
4.3 INITIAL SWITCH-ON / FUNCTIONAL TEST
Target: achieve rotation of the motor connected to the drive as quickly as possible. Requirements:
– The connected motor matches the drive in terms of power.
– The parameter settings comply with the delivery status.
1. Preparation:
1. Wiring of power terminals. (Chapter 4.2 Electrical installation).
2. Wire digital inputs X3/DI1 (start enable), X3/DI3 (reversal of rotation direction), and X3/DI4 (preset setpoint 20 Hz).
3. Do not connect terminal X3/AI1 (analog setpoint selection) or connect it to GND.
2. Switch on mains and check readiness for operation:
1. Switch on mains voltage.
2. Observe LED status displays "RDY" and "ERR" on the front of the drive:
a) If the blue "RDY" LED is blinking and the red "ERR" LED is off, the drive is ready for operation. The controller is inhibited.
You can now start the drive.
b) If the red "ERR" LED is lit permanently, a fault is pending.
Eliminate the fault before you carry on with the functional test.

blinking fast (4 Hz) Drive inhibited, warning active.
on Drive inhibited, fault active.
on off Drive enabled. The drive rotates according to the setpoint specified.
blinking fast (4 Hz) Drive enabled, warning active.
blinking (1 Hz) Drive enabled, quick stop as response to a fault active.
Carrying out the functional test
1. Start drive:
1. Enable drive: X3/DI1 = HIGH.
a) If the drive is equipped with an integrated safety system: X1/SIA = HIGH and X1/SIB = HIGH.
2. Activate preset setpoint 1 (20 Hz) as speed setpoint: X3/DI4 = HIGH.
The drive rotates with 20 Hz.
3. Optional: activate the function for the reversal of rotation direction.
a) X3/DI3 = HIGH.
The drive rotates with 20 Hz in the opposite direction.
b) Deactivate the function for the reversal of rotation direction again: X3/DI3 = LOW.
Speed characteristic (example)
2. Stop drive:
1. Deactivate preset setpoint 1 again: X3/DI4 = LOW.
2. Inhibit drive again: X3/DI1 = LOW.
The functional test is completed.
Drive follows the frequency setpoint
