Float 2
Displays maximum output current of converter.
Dependency: r0209 depends on the derating which is affected by pulse frequency P1800, surrounding temperature and
altitude. The data of derating is given in the Operating Instructions.

P0210 defines the supply voltage. Its default value depends upon the type of converter. If P0210 does not
correspond to the supply voltage, then it must be modified.
Dependency: Optimizes Vdc controller, which extends the ramp-down time if regenerative energy from motor would
otherwise cause DC-link overvoltage trips.
Reducing the value enables controller to cut in earlier and reduce the risk of overvoltage.
Set P1254 ("Auto detect Vdc switch-on levels") = 0. Cut-in levels for Vdc controller and compound braking
are then derived directly from P0210 (supply voltage):
•
Vdc_min switch-on level (r1246) = P1245 * sqrt(2) * P0210
•
Vdc_max switch-on level (r1242) = 1.15 * sqrt(2) * P0210
•
Dynamic braking switch-on level = 1.13 * sqrt(2) * P0210
•
Compound braking switch-on level = 1.13 * sqrt(2) * P0210
Set P1254 ("Auto detect Vdc switch-on levels") = 1. Cut-in levels for Vdc controller and compound braking
are then derived from r0070 (DC-link voltage):
•
Vdc_min switch-on level (r1246) = P1245 * r0070
•
Vdc_max switch-on level (r1242) = 1.15 * r0070
•
Dynamic braking switch-on level = 0.98 * r1242
•
Compound braking switch-on level = 0.98 * r1242
Auto-detection calculations are only performed when the converter has been in standby for over 20s.
When pulses are enabled, the calculated values are frozen after pulses are ceased for 20s.
Note:
For best results, it is recommended that auto-detection of Vdc switch-on levels (P1254 = 1) is used. Set-
ting P1254 = 0 is only recommended when there is a high degree of fluctuation of the DC-link when the
motor is being driven. In this case, ensure the setting of P0210 is correct.
If mains voltage is higher than value entered, automatic deactivation of the Vdc controller may occur to
avoid acceleration of the motor. A warning will be issued in this case (A910).
Default value is depending on converter type and its rating data.

Indexed parameter to display maximum allowable cable length between converter and motor.
Index:
[0]
Maximum allowed unscreened cable length
