(3) Operation voltage (torque) setting [Pr. 12]
Use [ Pr. 12 ] to set the percentage to the power supply
voltage. (For , this parameter is not used
during zero speed control or servo lock.)
When [
Pr. 12 = 0%], the DC injection brake is
disabled. (At a stop, the motor coasts.)
Even [
Pr. 12 ] setting is set larger, braking torque is
limited so that output current is within the inverter
rated current.
When using the constant-torque motor (SF-JRCA)
and energy saving motor (SF-HR, SF-HRCA),
change the [
Pr. 12 ] setting as follows:
For the 5.5K, 7.5K, when the [ Pr. 12 ] setting is the
following, changing the [ Pr. 71 Applied motor ] setting
automatically changes the [ Pr. 12 ] setting. Therefore,
it is not necessary to change the [
Pr. 12
] setting.
SF-JRCA: 3.7K or less ...4%, 5.5K to 55K ...2%
SF-HR, SF-HRCA: 3.7K or less...4%, 5.5K, 7.5K...3%,
11K to 55K...2% (30K...1.5%)
