Product Description

The Kollmorgen S7720C-DNF2-S4 digital servo amplifier must be re-formed if it has been in storage for more than a year. This servo amplifier must be operated with the control cabinet closed. The product portrays a 1K4 storage class according to EN 61800-2 and EN60721-3-1 specifications. This device must have adequate free space above and below it inside the switchgear cabinet. The unit has a tightening torque of 0.5 Nm for its mounting flange. Its PC interface connector is a male SubD 9-pole connector with a maximum cross-section of 0.5 mm2. This amplifier comes with Ethernet connectivity onboard.

The product can be paired with different types of motors from the manufacturer. The device is also compatible with a third-party stepper motor controller. This unit may cause unfavorable consequences such as property damage or personnel injury if it is not used as intended. Its electrical installation must be undertaken only by people with expertise in electrical engineering. The amplifier should be installed, commissioned, and operated only after reading and understanding its manual. This product is likely to get damaged if its permissible voltage and current ratings are exceeded.

The device is prevented from unintentional restart by means of the STO function. This unit has a separate switching action for each STO enable input by the output of a safety control. It must be operated through an isolating transformer when protection against indirect contact is essential although an alternative form of shock-hazard protection is sought. The servo amplifier comprises several electrostatically sensitive components. This product must incorporate a copper mesh tape between the earth potential and earthing bolts to deflect currents in unfavorable situations.
