7. Cautions in Operation
7.2
Caution for when setting to 60% or more of RCP2-RA8 pressing current limit value
When the pressing current limit value, which determines the pressing force of the pressing operation, is
60% or less, continuous pressing and continuous operation are available.
Set the pressing current control value to the following.
Ɣ PCON Controller: Pressing setting in Position Table
The pressing current limit value can be set up to 70%.
When setting to a value from 60% to 70%, have a calculation to see if it satisfies the following operation
conditions to check if the continuous pressing and continuous operation are available. If continuous
pressing and continuous operation are not available, try to shorten the pressing duration and stop duration
so the setting satisfy the operational conditions.

once in 1 cycle.
Caution: When operating with the pressing current limit value from 60% to 70%, make sure to satisfy
the operational condition.
Not satisfying the operation conditions may generate excessive heat on the motor and may
result in serious damage.

Operational Conditions
1) Condition 1
Either the pressing duration or the stop duration against the current limit value is less
than the maximum duration.
The maximum duration of pressing duration and stop duration against the current limit value is shown
in Table 1 and Graph 1.
Confirm that the pressing duration or stop duration against the current limit value is less than the
maximum duration.
