Control Units

	Closed-loop control types S120	Open-loop control types S120	Main functions S120 for booksize/chassis formats	Comment, note
Infeed Control	Booksize Current control witt/without mains sensor V_DC control with/without mains sensor Chassis Current control with mains sensor V_DC control with mains sensor	Booksize Smart Line mode can be selected Chassis None	Mains identification Controller optimization Harmonics filter Integral reactive current compensation can be activated for the drive components Automatic restart	The mains sensor is the VSM10 Voltage Sensing Module; "current" is the line current; 3-phase with line frequency¹⁾
Servo control	Asynchronous motor Torque control with encoder Speed control with/without encoder Synchronous motor, linear motor and torque motor Torque control with encoder Speed control with encoder For all motor types Position control with encoder	Linear/parabolic characteristic Fixed-frequency characteristic (textiles) Independent voltage setpoint input	Data set changeover Setpoint input Motor identification Damping application Reduced magnetic flux in the asynchronous motor for reducing the thermal load on the machine Technology controller Basic positioner	The position control can be selected as a function module (stand-alone drives)

¹⁾ Operation of a Voltage Sensing Module is not approved with a SINUMERIK system.
