Entries in the power
module table
(inverter.inv)
 NAME: Designation of the power module
 PWM: PWM frequency in [Hz] at which the power module is driven
 S: Switch position of the current sensor. Is required for the D series of
HEIDENHAIN inverters (UM 1xx D) in order to use the higher currents
named above at the lower PWM frequencies.
Input 0 or 1
 I-MAX: Maximum current of the inverter output in [A]
 I-N: Rated current of the inverter output in [A]
 U-IMAX: Current sensor voltage in [V] at I-MAX
 I-N-DC: Permissible continuous current in stationary rotating field or until F-
DC is reached in [A]
 T-DC: Time constant, how long maximum current can be applied to a
stationary synchronous motor in [s]
 F-DC: Lower motor cutoff frequency down to which the motor can be loaded
with I-N-DC in [Hz]
 T-AC: Cycle duration for the duty cycle S6-40% in [s]
 F-AC: Motor frequency from which I-MAX is permissible in [s]
 T-IGBT: Protection time of the IGBTs in [s]
 R-SENSOR: Resistance of the current sensor. The entries in this column are
maintained by HEIDENHAIN and need not be changed by the machine tool
builder.
 F-Limit: Lower frequency limit
