List of parameters
p1830 Compensation valve lockout time phase W / Comp t_lock ph W
Access level: 4
Can be changed: U, T
Units group: -
Min
0.00 [µs]
Description: Sets the valve lockout time to compensate for phase W.
p1832 Dead time compensation current level / t_dead_comp I_lev
Access level: 4
Can be changed: U, T
Units group: -
Min
0.0 [Arms]
Description: Sets the current level for the dead time compensation.
Above the current level, the dead time - resulting from the converter switching delays - is compensated by a previ-
ously calculated constant value. If the relevant phase current setpoint falls below the absolute value defined by
p1832, the corrective value for this phase is continuously reduced.
Dependency: The factory setting of p1832 is automatically set to 0.02 * rated drive converter current (r0207).
p1900 Motor data identification and rotating measurement / MotID and rot meas
CU240D-2_DP Access level: 2
CU240D-2_DP_F
Can be changed: C(1), T
CU240D-2_PN
Units group: -
CU240D-2_PN_F
Min
0
Description: Sets the motor data identification and speed controller optimization.
The motor identification should first be performed with the motor stationary (p1900 = 1, 2; also refer to p1910).
Based on this, additional motor and control parameters can be determined using the motor data identification with
the motor rotating (p1900 = 1, 3; also refer to p1960).
p1900 = 0:
Function inhibited.
p1900 = 1:
Sets p1910 = 1 and p1960 = 0, 1 depending on p1300
When the drive enable signals are present, a motor data identification routine is carried out at standstill with the
next power-on command. Current flows through the motor which means that it can align itself by up to a quarter of
a revolution.
With the following power-on command, a rotating motor data identification routine is carried out - and in addition, a
speed controller optimization by making measurements at different motor speeds.
p1900 = 2:
Sets p1910 = 1 and p1960 = 0
When the drive enable signals are present, a motor data identification routine is carried out at standstill with the
next power-on command. Current flows through the motor which means that it can align itself by up to a quarter of
a revolution.
p1900 = 3:
Sets p1960 = 0, 1 depending on p1300
This setting should only be selected if the motor data identification was already carried out at standstill.
When the drive enable signals are present, with the next power-on command, a rotating motor data identification
routine is carried out - and in addition, speed controller optimization by taking measurements at different motor
speeds.
