Hardware

IUnom.: unit nominal current IUP: unit peak current IMnom.: motor nominal current

Dynamic monitoring:

In COMPAX, the nominal current value is limited to the smallest value of the following 3 quantities.

♦IUP: ♦ unit peak current

♦ P105 * P107: ♦ nominal motor current (P105) * maximum pulse current permitted for the motor (P107)

♦P105 * P16: ♦ nominal motor current (P105) * maximum permitted (user-set) torque (P16)

Static monitoring

This executes triple monitoring:
Unit monitoring	Using the unit-specific time constant TG, a current greater than
	IUnom. is permitted for a specific period; E53 then switches the unit
Motor monitoring	off.
	Using the time constant TM, a current greater than 1.1 * IMnom. is
	permitted for a specified period; E53 then switches the unit off.
	TM is set so that the pulse current P107 can flow for the period set
Final stage / short circuit monitoring	in P108.
	Absolute monitoring to 1.5 * IUP.
