Abstract
The emergency terminal stopping speed is checked by comparing (30) the number of pulses (26) provided by an encoder (10) driven by the elevator motor (12) with a fixed number (36) which for the particular elevator will correspond to the maximum allowable speed when received within a time frame determined by the overflow (46) from a presettable (44) counter (40). The time period is adjusted for each elevator installation so that the fixed number of pulses relate to the desired speed by adjusting the preset of the presettable counter. Floor leveling speed is also determined by comparing (32) the counted number of pulses with a settable (38) number.
