The user can modify the control operation parameters.
You can obtain safer, more reliable control characteristics by various type
of alarm output settings and settings such as overcurrent limit.

Note 1

Both ramp lower limit and ramp higher limit cannot be allocated to VR1
or VR2 at the same time.
If one VR has been selected, the other is automatically selected as well.
(Example: If ramp lower limit is set for VR1, only VR2 can be selected
to set ramp higher limit by VR.)
To change while higher or lower limit is selected, first cancel VR
allocation and then change.
(VR cannot be selected while using key sequence

‘

To allocate to ramp lower limit, cancel allocation of VR of key sequence

)

Note 2

Ramp lower limit cannot be set higher than ramp higher limit. (Key
setting and VR setting)

1-7. Ramp higher limit selection

Sets allocation of ramp higher limit of output (high power).

: Allocated to ramp higher limit only

: Allocated to VR1 x ramp higher limit setting

: Allocated to VR2 x ramp higher limit setting

Note 1

Both ramp lower limit and ramp higher limit cannot be allocated to VR1
or VR2 at the same time.
If one VR has been selected, the other is automatically selected as well.
(Example: If ramp higher limit is set for VR1, only VR2 can be selected
to set ramp lower limit by VR.)
To change while higher or lower limit is selected, first cancel VR
allocation and then change.
(VR cannot be selected while using key sequence

‘

1-11. Current limit.

’

To allocate to ramp higher limit, cancel allocation of VR of key

Note 2

For VR setting, ramp higher limit has priority if ramp higher limit is
lower than ramp lower limit.

Note 3

If allocating to VR1 or VR2, ramp higher limit is ramp higher limit setting
