<Example>

NR = 4 (rps)

I1 = I3 = 9 (A) I2 = 3 (A)

t1 = t2 = t3 = 1/4tCY

When calculating from the above setting example,

η B =	4	1 tCY		2 tCY		1 tCY			⋅	1	⋅ 100
	2	( 4		+ 4		+ 4		)		5tCY
=	2	⋅ 100 = 40
	5
η C =	(	81tCY	9 tCY		81 tCY		)	⋅		1	⋅ 100
		4	+ 4		+ 4				225tCY
=	17100		= 19
	900

When substituting the above into equation (3),

40 + 2.6 ⋅19 = 98 < 103

Therefore, the result satisfies the equation, and the setting is deemed to be correct.

(2) Restrictions on the driver

The repeat frequency caused by the driver is restricted by the heat generation of the driver’s built-in regenerative resistor. If a repeated operation is performed using the pattern as shown in Figure 11.3, the repeat frequency, as shown in Figure 11.4, is restricted by the load inertia using the number of revolutions as a parameter.

If the load inertia exceeds 1 kgm2, or if it is necessary to use on DYNASERV DR5000B series (DR5030B, 5050B, 5070B) outside of the limits, please contact Compumotor'sApplications Dept.
