DRIVES FOR STEPPING MOTORS FOR ELECTRIC CYLINDERS SERIES ELEKTRO
6A - 140VDC DRIVE FOR STEPPING MOTORS, CODE 37D1442000
10A - 62VAC DRIVE FOR STEPPING MOTORS, CODE 37D1552000
These are two ministep bipolar chopper drives made by RTA S.r.l.
They come with a STEP & DIRECTION interface for piloting medium/
high-power two-stage STEPPING motors with four, six or eight terminals.
They consist of a board housed in a metal box, which does not require
external ventilation, and come with separate logic and power pull-out
Drive code 37D1442000 is characterised by a voltage range up to
140VDC, compact dimensions and considerable operating flexibility.
This drive can control STEPPING motors with a nominal current up to 6A,
the perfect choice for medium-power applications requiring a DC supply.
Drive code 37D1552000 is characterised by a voltage range up to
62VAC, compact dimensions and considerable operating flexibility.
This drive can control STEPPING motors with a nominal current up to 10A,
the perfect choice for medium-power applications requiring an AC supply.
