2.3 Connection of the controlThefollowinginstructionsmustbeobservedatconnection:
Attention Prevent EMC malfunctions• Use shielded / drilled cables• Lay shield on one side of the inverter onto earth potential• Install control cables and power cables separately (approx. 10…20 cm
distance); Kreuzungen im rechten Winkel verlegen• Toavoid interferencesaseparateshieldingmustbeprovided foranalog
and digital control lines. Depending on the use of the relay outputs, an ex-tra shielding is to be used, too.
• In case of inductive load on the relay outputs a protective wiring must be provided (e.g. free-wheeling diode)!
Theterminalsofthecontrolterminalstripandthetransmitterinputsarese-curely isolated in accordance with EN 50178.

3.1 Emergency stop according EN 60204By using suitable safety switchgear units, stop category 0 and 1 according to EN 60204 can bereachedbytheSTOfunctioninthesystem.Notechapter6forsafetyswitchgearunits.
Stop category 0 „uncontrolled stop“, i.e. stop by immediate removal of power to the actuators.
Stop category 1„controlled stop“, i.e. power to the actuators is retained to apply brakinguntil thestop isachieved.Theenergy isswitchedoffatstandstill.
Emergency stop to EN 60204 must be functional in all operating modes of the drive module. Theresetofemergencystopmaynotleadtoanuncontrolledstartofthedrive.

ThedriverestartsiffunctionSTOisnolongerreleased.Inorderto comply with EN 60204, it must be ensured by external meas-uresthatthedriverestartsonlyafterconfirmation.
Without mechanical brake the drive leads to coast; motor is free-wheeling. Additional protec-tive devices must be installed (e.g.locking systems) if damage to persons or property can occur.
Ensure coast of the motor
If danger to persons occur after switching off the motor control bySTO,theentrancetohazardareasmustremaincloseduntilthe drive stops.
Jerks in error case
In case of double malfunction it can lead to unwanted jerk, the rotation angle is depending on the number of poles of the se-lected drive and the gear ratio.

age.• Mechanical brakes must be installed additionally if external forces have effect to the drive
axis, e.g. vertical axes (hanging loads) or rotary axes with asymmetrical weight distribu-tion.
• For the protection against pollution (pollution degree 2) the installation of the units must be provided in environment with increased protection (e. g. control cabinet IP 54).
• MakesurethatnosmallpartsfallintotheCOMBIVERTduringassemblyandwiring.Thisalso applies to mechanical components, which can lose small parts during operation.
• Check the safety functions and error responses and generate an acceptance report after installation.
• The start-up can be preventedwith interruption of theSTO signals. STOmay not bereleased in case of danger according to EN 60204-1. Also note the instructions to the external safety switch devices.
• Dimension the safety application by way that the corresponding input current of the safety functions is available for the inputs (see chapter 2.5.1).

When pressing the emergency stop unit the drive is stopped with a deceleration ramp via input X2A.13 (I3).Simultaneously the expiration of the safe time occurs in the safety module. After expiration of the safe period the control signals STO1+ und STO2+ (X2B.1 and 5) are removed and thus the energy supply of the drive is disconnected.Thefollowingadjustmentsmustbedoneinthedrivemoduleforthefunction„drivestop“:Parameter Adjustmentpn29 „prg. error stop. mode“ (Index 0x2A1D) 1:dec.ramp->Faultpn48-59 (0x2A30-0x2A3C) Adjustment of the deceleration and jerk
