MOTOROLA MVME761-001 Channel intelligent module

Limit switch positive/negative (PSTOP / NSTOP, terminals X3/10 and 11), high level in normal operation (fail-safe for cable break). A low signal (open) disables the corresponding direction of rotation, the ramp function remains active. If the inputs are blocked the I-component of the speed controller will also become ineffective, so that a mechanical demarcation (dead stop) is permissible. This function must be explicitly enabled (parameter LIMIT SWITCH to ON). If the parameter LIMIT SWITCH is set to STOP, the result is a controlled drift-free standstill of the motor, with the standstill torque M0, when the limit switch inputs are disabled (I-component is active).

Analog outputs 

DC-monitor: armature current setpoint IDC and tachometer monitor output VTA Depending on the setting of the DC-MONITOR parameter, the IDC/VTA output (terminal X3/23) provides either the current setpoint (IDC) or a tachometer voltage (VTA). IDC preselection The IDC monitor provides
10V at
peak equipment current (sinusoidal rms value) referred to AGND. The output is the equivalent to the active current value, which is approximately proportional to the motor output torque. Output resistance: 2.2k, resolution: 8bit. VTA preselection The output provides
10V referred to AGND at the preset final speed limit. Output resistance: 2.2k, resolution: 10 bit.
