Chapter 7 Descriptions of Parameters
This chapter describes parameters of VF66B (DC motor drive). Each section of this chapter describes
parameters of each area.
7.1. Basic Setting Area
In the basic setting area, the common-used basic setting items to operate VF66B (DC motor drive) are shown
below.
In this area, you can set operating speed and adjust normal acceleration or deceleration time from the
console.

Speed command (0.SrEF):
Set this parameter when the operation speed is set using the console panel. This parameter is enabled when
the console panel is selected for the command input when coupled (b-09) and the interlock is selected for the
speed/armature voltage command input selection (b-10), and when the console panel is selected as the
speed commanding place in the speed/armature voltage command input selection (b-10). Refer to "6.4. Area
b" in Chapter 6 and "7.4. Area b" in Chapter 7.
Forward/Reverse JOG speed (1.FJoG/2.rJoG):
Set the forward or reverse jog speed.

Set the acceleration time from 0 to the Maximum speed

and the deceleration time from the
Maximum speed
＜
A-00
＞
to 0. VF66B (DC motor drive) has four types of acceleration/deceleration time,
and you can switch to one of them using the acceleration/deceleration time selection (d-00) and JOG
acceleration/deceleration time selection (d-01). (At the initial settings, acceleration/deceleration times (1)
(3.Acc1 and 4.dEc1) are for the normal operation and acceleration/deceleration times (2) (5.Acc2 and 6.dEc2)
are for the JOG operation. For more information about acceleration/deceleration time settings, refer to "6.5.
Area d" in Chapter 6 and "7.5. Area d" in Chapter 7 together with this section.)
