CHAPTER 4 PARAMETER

Extended Function Setting Parameter

(*1) Free-run causes deceleration upon major failure alarm.
Specify the deceleration and stopping states for each condition as shown in the previous table.
PA2_64 Torque keeping time to holding brake
No. Name Setting range
Default
value
Change
64
Torque keeping time to
holding brake
0.00 to 9.99 [s] 0.00 Always
Assign the "brake timing" signal to the output signal.
The reference value of this parameter indicates the delay taken from shutoff of servo-on (CONT input
signal, function no.1) to free-run.
Specify a time larger than the one taken from excitation of the brake to actual brake application.
The brake timing signal is turned off when servo-on is turned off.
PA2_65 Regenerative resistor selection
No. Name Setting range
Default
value
Change
65
Regenerative resistor
selection 0: None
1: Internal resistor 2: External resistor
1 Power
Select the regenerative resistor.
If the reference value is 1, the temperature of the regenerative resistor is calculated inside the amplifier
and monitored as a regenerative thermal value. 100% indicates an overheated internal regenerative
resistor (RH1).
To install an external regenerative resistor for elevator operation or high operation frequency, set at 2.
If the reference value is 2, connect the thermistor of the external resistor to the external regenerative
resistor overheat (function no.34).
Because of a normally closed contact, shutoff indicates an external regenerative resistor overheat
(RH2).
PA2_66 Flying start at speed control
No. Name Setting range
Default
value
Change
66
Flying start at speed
control 0: No flying start
1: Flying start
0 Power
The parameter is enabled under speed control.
If servo-on is turned on during free-run operation, the speed at the timing is picked and acceleration
begins at the speed.
The speed at the timing of power-on is not picked in this case.
