MESA Automation GmbH RECEIVING AND HANDLING Upon delivery of the equipment, inspect the shipping containers and contents for indications of damages in curried in transit. If any of the items specified in the bill of lading are damaged, or the quantity is incorrect, do not accept them until the freight or express agent makes an appropriate notation on your freight bill or express receipt. Claims for loss or damage in shipment must not be deducted from your invoice, nor should payment be withheld pending adjustment of any such claims. Store the equipment in a clean , dry area. It is advisable to...

The MS servo modules are extremely compact PWM servo amplifiers that provide 4 quadrant speed control of any DC servo motors with Tacho or with BEMF feedback. MS amplifiers are conceived for regulation of brush DC motors. The MSMN... power supply transforms ac voltage into dc voltage. From dc voltage...

MESA Automation GmbH 3.1 Subprint OPT E Limit switch By connection of GND (OPT E -) or 24 V signal (OPT E +) to the terminals for negative and positive direction the limit switch can be deactivated. If the limit switch is active, the motor will stop in these direction. The limit switch logic level (OPT E += positive, OPT E (-)= negative logic) is set by factory. R 111 must be removed, otherwise option B;C and E will not work. 3.2 Subprint MSM-OPT Other Options are available by using MSM-OPT Subprint- please ask for more information. - external current limiting, positive and negative Output current...

MESA Automation GmbH T ransformers with galvanic separated primary an secondary winding are used for adjustment of supply voltage to the existing net. The Transformers have to correspond to VDE 0550. One and three phase transformers can be used. If the transformer used has a star point in its secondary winding then this should be isolated and NOT connected to earth. A three phase transformer is recommended for current higher than 10 a continuos overall. The factory or your dealer should be consulted to specify the proper size and secondary voltage. The adjustment of Tacho, output current, Irms...

MESA Automation GmbH 5.3 Adjustment of the speed controller gain Amplifiers are equipped with a standard optimisation and can be adapted by P2. Is this adjustment not possible, PI on the Personality card must be checked.

MESA Automation GmbH 5.4 Armature Current Measurement Armature current is measured by means of a shunt placed in series with the armature circuit. The voltage produced can be measured at the „I Monitor“ test point. 10 Volts output corresponds to the maximum current of the amplifier. Max. Output current IAmax: P4 The amplifier is capable of supplying twice is rated current for 1.5-5 seconds. Peak current will be adjusted by P4. Standard-Range: Right side: Left side: IAmax = 1 x Imax = Type-max. current IAmax = 0,03 x I max Current balance: P7 Adjustment of the internal Current measurement! Set...

MESA Automation GmbH Monitoring over voltage If over voltage occurs in the DC Bus voltage, a fault is signalled. Monitoring under voltage The +/- 15 V will drop to 0V DC an disable the amplifier. Monitoring over temperature of the power stage Monitoring of the heat sink temperature up to 90 ° C or 190 ° F • It is Important that the amplifier (Rack or stand-alone) is properly earthed. If the amplifier is not earthed then if an earth fault occurs in the motor circuit the output of the amplifier will be destroyed. • Each motor must be wired separately (cable should be shielded) • Motor cable may...
